Some USB-connected devices don't show up as drives
When I connect the following devices to my computer, through any USB
port, they are not recognized as drives, and don't show up in Explorer.
- Digital Camera
However, the problem does not show up with the following devices - the are recognized as removable disk drives:
- External hard disk
- Oakley Sunglasses with built in flash drive and MP3 player
Neither show up as drives, but they show up in the Device Manager,
under Portable Devices and both show the following message in its
"Windows cannot start this hardware device because its configuration
information (in the registry) is incomplete or damaged. (Code 19)"
With the iPhone, even though it does not show up as a drive, iTunes is
able to recognize it and sync it. However, Vista Home Premium SP1's
Explorer is unable to detect it.
I've reinstalled iTunes and installed and used TweakVI, but to no avail.

Re: Some USB-connected devices don't show up as drives
This is not unusual windows will only recognize the standard memory cards not any custom ones or inbuilt ones. For example if your device is using a SD memory stick it will show up in explorer however if you are using a device that has a copyright or custom it wont. I am surprised the digital camera is doing the same thing as thy use mmc cards which are standard and should show up.
With these devices when you connect it to a pc you would get an option on the lcd on the device that would need you to confirm connection. may be thats what you were looking for. If you have a memory card reader you can try using that as well.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Get another lead Some external storage devices work poorly or not at all when connected to a hub; try connecting the drive directly to a port on the computer. Also check if it's detected in "Disk Management". Here you can verify if the partition and format are correct for the Operating System. Check the Drive's status in Device manager. This will verify if the external drive has a drive letter designation. Check Partition and Format. Log in as Administrator account in windows or any other account with administrative privileges Insert your removable disk into the USB port. Click Start, right click on computer and select manage. Now, click Disk Management. Check whether drive letter for the device is present. Check the lower window to find whether the device is detected (such as Disk 1, Disk 2, etc). If the device is detected with a drive letter, verify that no other device is using that drive letter. If it is, change it to unused drive letter. Hope this helps.
No question is silly dear, problems are there and we are in this site to help.
Yes, you mentioned that the said device works fine with your desktop, then it is probably not the problem with your device. You have also said that your tried formatting the os. Good.
Hope your pc, laptop and the memory device are disinfected with a good, licensed and updated antivirus.
Check, if Universal Serial Bus Controllers (corresponding to the nos. of total usb port present in the machine) are present and enabled both in the device manager and the bios as well and set to Hi-Speed if it is Full-Speed.
Well, have you tried formatting the memory stick/device? Format it and see if it works.
Next, please change the usb connectivity cable using/attached to the device and see.
Another thing while connecting an external storage device like ext-hdd. The external usb storage devices that gets connected with a usb cable, in some rare cases needs to be connected as a usb-master or usb-slave [you can see many external usb drives comes with a splitted or dual usb port connector cable, this is either for connecting two usb device or to connect as master when used as a single drive], therefore use such cable to connect and use alternated ports, and see which works.
Now, if all above fails, it then might be the problem with your external drive, i guess.
camera on, don't connect it to usb port, yet. After it turns on, push
menu button, now connect it to your usb port. Disregard when it asks
about installing driver software. If you follow these steps your
computer will recognize it as another drive and ask open folder to view
Merry Christmas!!! Greetings for the festive seasons! It seems like you are connecting a USB device to our computer. USB is a PNP bus. whenever you connect anything to USB, some handshaking is done by the OS with your USB device, so as to recognise its class (if it is a storage device or printer etc,) and other details like its manufacturer, capacity etc. If, for any reasons, this handshaking is not done, this error is raised. to solve this problem, try following things 1. change cord and try again. 2. If it is a USB hard disk, try twin USB cable. where single USB end is connected to the USB hard disk, and twin USB side (both the pins) are connected to the. PC. It happens, when device is consuming more power, so some additional power is needed to drive it. 3. If it is a mobile, printer or camera, install drivers first and then connect the device. 4. If you are connecting it to front USB ports and the wiring inside is made incorrct. This nmay cause damage to any device you connect to that port. if any other product is working on that port, then simply rule out this probability 5.Try different port, as the device you are using may be using higher version (USB 2.0 or USB 3.0). but this is rare case, as PC itself will prompt you by "This device can work faster" 6. Device itself is faulty. try connecting, similar device to your PC and confirm. If it is not solved, give brief description of what are you connecting to your PC and what have you tried before.
have you tryed other usb ports? try goign to device manager, right click on my computer icon on the desktop click on then click on manage then click okay if a window pops up, now once computer management opens look at three options click on system tools then another list will show then click on device manager that should show if the system has read it or not normal if it doesn't reconize it will show a yellow question mark same as inproper install of driver. Also try getting the driver fo it and install driver first then connect that too can be a problem. hope this helps.
You have to do some steps about fixing this problem :
1: Go to Device manager by right click on my computer then manage and then device manager.
2: Go to universal serial bus controller and export it.
3: in each USB root hub right click and then properties.
4: In properties screen select power management tab and unmark on " allow the computer to turn off this device to save power ".
5: After finishing this steps in each USB root hun restart your computer and then done
You might think about a USB hub for all your USB devices. ps2 port is more or less dedicated for mouse, which is why your mouse pointer is stuck in the middle of the screen. Go ahead and get an externally powered USB Hub to power other USB devices. To answer, ps2 for mouse needs just a mouse, not USB device.
