Hi, I just acquired one of these cards, it attaches as a USB cardbus device. This is just to say that I can reproduce the problem described here: http://www.rinta-aho.org/docs/option3g/option.html The driver support was originally committed here: http://www.freebsd.org/cgi/query-pr.cgi?pr=112161&cat ...the ubsa driver attaches to the virtual modem port. If I unplug it, the kernel panics. The panic is in kobj_delete() (a null pointer reference) and it's on the usb detach path. Unfortunately I wasn't able to get a backtrace this time around. PS Does anybody know if ubsa will be ported to the new USB driver framework? cheers BMS

The card contains an OHCI controller, but the ohci(4) driver doesn't support detaching. I think that's also the reason why you have to compile ohci statically in your kernel, there's no module for it. Solution: Don't unplug the card. The problem is supposed to be fixed with usb4bsd, but I haven't tried it myself. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
