My modem gives a response on usb device not detected every time i insert it in a computer


Well theres one of two problems here, the device is either not working properly or your usb port/card may be shot... Either or try using other usb ports and if this issue continues then try it on another computer...

The laptop can not detect device when you try to connect the GPRS 3g


Try connecting it to a different port.
Also check whether your USB ports are working using any USB devices.
If the ports are working and the 3G modem is not getting detected, then you should try replacing the modem.

Does it matter which usb port I connect a printer cable to?


No problem as to which port you plug in, but make sure the Com port/RS-232/USB Port is enabled to detect the hardware. The device won't detect the hardware if you haven't made the changes in BIOS or port enabled in device manager (system properties>hardware). Hope this solves the query.

My usb modem [lemon 3g] does not get detected. when i plug the modem it does not show anything i.e usb icon detected hardware etc. when i clikc on cmy computer also it does not show any connection why is...


First, check for the power source, there should be a light indicator on the panel of the modem, else, power is a problem, check your adapter/power cable. Next, is use USB cable/USB port, try to use other USB cable/USB port. Another option is to check your Control Panel - Device Manager, see if there is a USB Modem currently installed. Remove/delete the device from your Device Manager. Going back to Control Panel, select Add Hardware. If still fails to detect, your Modem is dead.
Good luck.

Why can't my PC detect Garmin 255W when I plug it via USB?


First makre sure that the usb is working. Just plug anythign into the usb port and if it detect it we know that is working.

Now with the GPS plug the usb cable into the port you tested then plug the gps on the other end. Watch your screen (PC) and see if it detects the gps. It should say one of two things. One will be device discovered Garmin GPS (something along that line) or it may show USB storage device. You can plug it in and look under my computer for these if you missed what it said. Some versions of windows are better than others at detecting whats connected. And some hardware is better than other at detecting something on a connected usb cable.

You should also plug the cable into a differant port if you had left it connected and were getting this problem. And you should try plugging both into a differant computer if you can. Doing these can tell you if the problem is the gps, the cable the port or the computer itself. Usually just changing the port is all it takes.

Cant detect the device


Most likely why that isn't working correctly is because your usb port on your computer is most likely bad... I know someone who had the same problem and once she plugged the player into another usb port it worked like a charm.

Hardware detection problem


Can you explain a bit better? Sometiems it's detected, but there's no detection?

Try plugging it back in. Go to Start: Run: devmgmt.msc orStart: bar at the bottom, type devmgmt.msc ... Look at your devices, look at whether anything has a warning sign next to it.

USB powerloss?


As you have already stated that the port in question can run a standard optical mouse, the port seems to be working fine.

Sometimes the drivers for a USB device need to be installed for each USB port. Maybe you have installed these drivers for 3 of your 4 USB ports, but not for the one in question, result of which is the problem you face.
