Using FC1 on a Latitude CSx this card simply froze the machine on insertion. When removed, the laptop carried on where it left off. No log entries were made. No clue available in the system as to what went wrong. it just doesn't work in this machine under FC1.

This card is based on the ALi chipset.

For the 2.4 kernel, as above (I found that my machine froze whilst the card was insterted.) Not suprising given that USB 2.0 support is more limited in the 2.4 kernel..

For the 2.6 kernels I tried, the PC Card was detected, but there was an error with the interrupt (irq). The interrupt was disabled (this caused problems for other devices sharing that interrupt.). Devices plugged into the PC Card were not detected.

I thought it might have been a resource conflict on my machine. However, I bought a 4-port USB 2.0 CardBus card based on the NEC chipset and that works perfectly with the 2.6 kernel.
