Hi. My computer doesn't recognise any of my usb devices any more. They were working one day and then not the next. I think it has something to do with me finding my 3 year old who had turned my computer on and managed to rename some folders on my desktop. I dont know if he has renamed other vital files. I tried the removing of the root hub and rebooting and still can not connect. Please Help. firstname.lastname@example.org

Have you tried to use the mouse in another computer to determine that the mouse if fully working. There are many reasons why it could be non-recognised. Has it ever worked on your system? Is it new and just a faulty mouse. It may be you could just take it back to the shop for a replacement one. Do other devices work in the same USB port. Some times my computer just stops recognising my USB keyboard yet it has been working for months. I found that it seems to be the USB port where the problem is. So not I just switch my mouse and Keyboard usb connectors around and it starts to recognise both again. I can not figure out why it stops. As another device is recognised suggesting the port is not faulty.
i would think the psu is failing and needs replacing, using the usb is just putting to much stress on the psu. the psu controls the power and if one is not working right it affects the psu's out put on all power outputs.
Several conditions affect how the USB device functions. First, unplugging the USB device least with the prescribed method of shutting resources with the menu buttons provided on computer makes device loose components recognisable at replugin. usually, in such instance the computer takes time to reconfigure the device at reconnection either automatically installing mutated codes or requesting to manually download the fragmented codes. Second, computer that have undergone updates or upgrades prior to establishing the USB devices least recognies the device. Reconnect the device to momentarily reconfigure the new setting attained on computer. Depending on the type of modifications that were made to the computer would either autocompile the USB codes to attain functionality or require manual installation of missing programs. usually the computer has the recommended missing programs only requires unpacking at the system update search buttons. In the sitaution where the computer was modified beyond recognising USB device require to ascertian that compartible ssytems would allow install a program from elswhere or simple acquiring another computer thar recognises the USB device.
if it works on the onboard usb.
Theres a chance that either the pcmcia slot drivers are incorrect, or the actual slot is faulty.
Try it in another slot, if you have 1.
update any onboard device drivers. if applicable. try the card in a different laptop. to eliminate the card. alternatively, try a different card in the slot. wifi card et,c.
hello there. It sounds as if your motherboard (bios) is not configured correctly, or your windows drivers somehow got corrupted. check in your MoBo's manual to see how to access it's bios options. and make sure that your onboard usb options are enabled.
