Hi, I have a problem with an usb2 cardbus controller on a Siemens Mobile 510 laptop. I'm not sure if this is really usb-related, but maybe anyone has an idea what I can try to get at least some error messages. The controller (NEC) works fine with kernel 2.6.1 on a Samsung X10 laptop, but it is not working with kernels <= 2.6.1rc1. (I didn't try rc2) On the Siemens it does the following with 2.6.1: - the controller is recognized and three devices (two OHCI and one EHCI controller) are added to lspci - the usb bus looks also good and both the ohci and ehci modules load correctly - if I try to attach some device (no matter if it is an 1.1 or 2.0 device, and if I load ehci or just ohci) it is detected correctly and looks normal in lsusb -v. - I can mount mass storage devices, but most of the time an ls /mnt is enough to freeze the whole system. Any ideas what this _could_ be?
