Hi Dominique, Thanks for your suggestion and help. I've tried my VIA VT6212L USB2.0 PCI card on other Linux system(x86 based) (RedHat 7.2 + kernel 2.4.16). And it works fine under kernel 2.4.16 with an USB patch from kernel 2.4.26. So I migrated the system to MIPS, but I was stuck by this problem. Altough I'm not familiar with device driver, but I will try Jan-Benedict's suggestion.
