I have tried to make a "Soundblaster X-FI Expresscard" work with Fedora 10 but failed. Once the card is insert, it seems it will be recognized but still something goes wrong what is far beyond my knowledge.
dmesg output says:
usb 4-2: new full speed USB device using uhci_hcd and address 3

so is there somebody who is able to decipher what is going on here or could point me in any direction where to start to solve this problem. Any help is highly appreciated.
