USB port killing memory sticks

[Baz]

Archived from groups: microsoft.public.windowsxp.hardware (More info?)

I have recently had a spate of USB pen drives dying. These drives have
been placed in all manor of machines. Tonight I plugged a brand new
drive into the USB port of my home machine, the PC detected it and then
decided it was faulty. Unplugging and plugging in the drive eventually
got it to work for a while but now the drive is completely dead
(Although it is detected as a non-functioning device).

I have plugged other devices into this port with no problems but I was
wondering if there is any way a USB port can go faulty in such a way as
to kill pen drives but nothing else.

The USB port was on a VIA chipset USB 2.0 PCI card.

Seeing as how the USB port supplies the operating voltage to the memory
stick, yes - it could be supplying excess voltage which could kill a device.
No, I do not know what the standard operating voltage for USB devices. (-:
