Question about Digital Blue QX5 Microscope

1 Answer

Error message: qx5 not connected, please plug in usb.

Trying to get this device working on Vista home premium. Have tried different usb sockets, even gone out and bought a powered usb hub. Have uninstalled and re-installed software. Have checked online for updated drivers. My knowledge of advanced settings is extremely limited, so I'm nervous of pushing any buttons in that area. At a loss. Can anyone help?

    Having the same problem, need a solution for Vista.

    My current solution is running the QX5 on my old computer using Windows 95 works fine but a bit slow.

Email Digital Blue and they will ask for your email address and shipping address. Looks like they're starting to send out the Vista version on cd via the mail, then make it available online for download later. Best of luck!

File transfer cable doe not recognize computer when connected to usb hub

Some USB hubs are "powered", some are not. If you have several different things plugged into the hub, you most likely need a powered hub, one that plugs into the wall for power. USB devices need power supplied over the USB cable, and one computer socket can't always supply enough power for several devices.

My computer tells me that if my wireless adaptor was plugged into a different USB root hub it would work faster. How is this done?

Try plugging the wireless adapter into one of the usb slots on the back of the computer. If it still shows that message, I wouldn't worry. The difference in speed is negligible at best. hope this helps

Seems that your laptop's USB ports are not providing enough power to the cooling pad. This could be due to you connecting too many USB peripherals to your laptop. Test if you can get the cooling pad to work by disconnecting all other USB devices.
As a permanent fix, you can buy an active USB hub (one powered by external power source) & connect your cooling pad to it.

109 error message when running microscope

According to the Digital Blue website, there are a variety of things that can cause this error, including USB configuration issues, QX5 connectivity problems, or an improperly installed device. To troubleshoot, try the following steps. If one does not work, try the next until the problem is resolved.
1. Exit from the application, unplug the QX5 from your computer, and restart your computer. Once your computer has rebooted, plug in the microscope and restart the application.
2. If you are using a USB hub (an external device that allows you to connect additional USB products to your computer), exit the application and plug the microscope directly into the USB port on your computer. If the microscope works when plugged directly into your computer, there may be a problem with your hub, or it may not be supplying enough power to run the microscope. If your hub does not have a power adapter, you will need to plug the QX5 into your computer's USB port or use a hub that is powered.
3. If you are not using a USB hub, try different USB ports. Always exit the application, unplug the QX5, and then plug into a new USB port. Wait at least one full minute to make certain that Windows recognizes the QX5. Then start the application again. If you are still experiencing the problem, try another USB device (if possible). If no USB devices are working, there is a chance your USB ports are not working properly and you should contact your computer manufacturer to resolve the problem.
4. If you have a laptop, make sure the laptop is using its power adapter. When running on battery, some laptop computers don't supply enough power to USB ports and as a result the QX5 will not work properly.
Note: The following steps require some experience with Windows computers. If you are comfortable modifying advanced settings on your computer (like the Device Manager or BIOS), proceed at your own risk. Otherwise, respond to this email and provide your phone number so a member of our technical support team can assist you.
5. Plug in the QX5. Go to Start > Settings > Control Panel and double click on the System icon. For each of the following items (if present), select that item, then click the Remove button:
  • Any devices that have a ? or ! next to them, or that are listed as "USB Camera Device."
  • The driver named "Digital Blue QX5™ Microscope #2" (located under Imaging devices).
After removing all the devices, click the Refresh button.
6. Try lowering the hardware acceleration of your video adapter. To do this, follow the steps below that apply to your operating system:
If using Windows 98, Windows 98 Second Edition, or Windows Me:
  1. Click on Start > Settings > Control Panel.
  2. Double-click on Display.
  3. Click on the Settings tab
  4. Click on the button labeled Advanced
  5. Click on the Performance tab
  6. -proceed to 'fix continued...
If using Windows 2000 or Windows XP (classic view):
  1. Click on Start > Settings > Control Panel
  2. Double-click on Display
  3. Click on the Settings tab
  4. Click on the button labeled Advanced
  5. Click on the Troubleshoot tab
  6. -proceed to 'fix continued...
If using Windows XP (XP style category view):
  1. Click on Start > Control Panel
  2. Click Appearance and Themes
  3. Click Display
  4. Click on the Settings tab
  5. Click on the button labeled Advanced
  6. Click on the Troubleshoot tab
  7. -proceed to 'fix continued...
...'fix continued'
While in the Performance tab, move the slider for Graphics Hardware acceleration one notch to the left. After you do this, the panel should indicate "basic accelerator function". Click OK, then click OK again to exit from the Display Properties window. Restart your computer and launch the QX5 software. If this does not fix the problem, repeat the process until all the available HW acceleration settings have been tried. (Different video adapters disable the acceleration at different points on the slider.)
7. Unplug your QX5 microscope and restart your computer in "Safe Mode." To get into "Safe Mode," you must reboot your computer and press the appropriate key before the Windows logo screen appears. If you do not know how to do this refer to your computer's manual or contact your computer manufacturer.
If you are successful in starting in Safe Mode, there will be a "Safe Mode" logo in each corner of your desktop. Then follow these steps:
a. Click Start/Settings/Control Panel.
b. Double-click the System icon.
c. Go to the Device Manager tab.
d. For each of the following items (if present), highlight the item, then click the Remove button:
  • Any device that has a ? or ! next it or is listed as "USB Camera Device."
  • The "Digital Blue QX5(tm) Microscope #2" driver (located under Imaging Devices).
e. Close the device manager, and restart your computer
f. Go to Start/Settings/Control Panel and double click the Add New Hardware icon.
Go through the Add New Hardware Wizard. When the Wizard asks if you want Windows to search for new hardware, select "Yes".
Note: You may be asked to insert your Windows CD or the CD that came with the microscope. If you are prompted to insert one of these CDs, you MUST do so or the microscope will not be properly installed. (Contact your computer manufacturer if you cannot find your Windows CD.)
g. When the new hardware installation is complete, restart your system, then try running the QX5 software again. 8. Uninstall the QX5 software (which will not delete any video or images you may have captured as long as you re-install to the same directory) by following these steps:
a. From the start menu, open the QX5 program group and select the uninstaller.
b. Follow the instructions to uninstall.
c. Restart your computer.
d. Insert your QX5 CD-ROM and follow the install instructions.
e. Plug in your QX5, wait a minute for Windows to recognize and install.
f. Start the application.

Saitek Pro Flight yoke and quadrant stop working

I had a similar problem with Vista Home 32. Finally tried an old external USB 1.1 hub that I had laying around and now everything works all the time in FSX and X-Plane. It is rock solid. Can't make it fail even when I try. I also tried a USB 2.0 hub but had the same problem with that. I can't say for sure it will fix your problem but it is worth a try.

USB upload error from Panasonic DMC-TZ4 to my laptop (Thinkpad T)

Are you trying to copy your photos off the camera, or use it as a webcam?
If you are trying to copy photos, then make sure the camera is in the correct mode, eg: playback mode. if the problem still occurs then try a different USB socket on the computer. If that doesn't work then possibly the USB socket on the camera is damaged (this is a common fault). I would suggest getting a SD card reader that stays connected to your computer full time, take the SD card out of the camera and plug it into the SD reader. That is a more reliable solution.

It may be that you need to update your drivers

Start here

Microsoft's built in drivers may not be making best use of your hardware and causing the problem you describe.

The driver may be for the motherboard and not usb.
Either way it provided you with the opportunity to update other drivers too
