"When i plug the usb flash drive into any of the 4 usb ports at the rear of my pc, the device is recognized & working properly."
Front USB ports on better than 90% of the machines I see have USB 1.1 type wiring and have caused such issues. While convenient I feel that this issue is doing a lot of people in.
Fix? Don't plug it in there.
I have 2 front usb & 4 rear usb ports on my pc. In july, i bought a 1gb usb flash drive brand new & sealed from Ebay. Up until a week ago, i had never had a problem with this device.
I plugged my usb flash drive into 1 of the front usb ports & nothing happened. No 'new device found' message. I checked in 'my computer' & 'device manager' & it wasn't there. I tried it in the other front usb port & 'usb device not recognized' appeared. Still nothing in 'my computer' but it was there in 'device manager' under 'universal serial bus controllers' it appeared as 'unknown device'.
I opened up the properties for the 'unknown device' to find it telling me that no drivers were installed with this device. I clicked on the driver tab & it has the following info:
Driver provider - Microsoft
= date - 01/07/01
= version - 5.1.2600.0
= signer - Microsoft Windows Publisher
So, there are drivers there for this device. I've tried to update the driver but was told "Windows couldn't find a better match for my hardware than the software installed".
When i plug the usb flash drive into any of the 4 usb ports at the rear of my pc, the device is recognized & working properly. If i then open the folder for the device the program stops responding & i have to end the task - which takes a long time as everything slows down.
When i can finally end the task, the following message appears:
"The specified I/O operation on\device\harddisk1\dr4 was not completed before the time-out period expired".
I've also had this message appear:
"G:\ is not accessible
the request could not be performed because of an I/O device error".
Please can somebody help me with this problem as my usb flash drive is, at this moment, useless & i'd rather not go out & buy a new flash drive. Thanks in advance.
