Flash Card USB Extension Cable troubles


Hello everybody,
I have a problem with my 1G USB flash memory stick (Transcend JetFlash). The problem is with the cable that went with the stick, or so I guess...
I am on Mandrake 10.1 (download edition).

When I plug it into the USB port without the cable it works:

tail -f /var/log/messages
==============================

==============================
And the indicator on the flash card lights on.

Then I am trying to do the same thing via the cable that went with the memory stick and it goes:

==============================

Nov 28 16:06:04 work kernel: usb 4-2: can't set config #1, error -71
==============================
The indicator on the flash card does not light on.

What could be the problem? The card works via the same cable on windows.

Since there are so many replies.... I thought that I post the solution I found. Maybe somebody will find it useful.

It appears that the power supplied to the USB port that was on the back of the motherboard was not enough for it to work normally and I had to use an active cable that I connected to the USB socket on the motherboard (it was a 9-pin connector). The cable aside from the data transfer also provides a power supply to the USB port (that is on the other end of the cable)

So, it works now with or without the extension cable.
