The moment I start lsusb, the keyboard LEDs light up and I can use the device normally, just like that. Thanks a lot! I'll just add lsusb to my usbhostmode.sh script now. :) Marcos Regards, Konstantin ___ support mailing list support@lists.openmoko.org https://lists.openmoko.org/mailman/listinfo/support

[FDOM, 2008.9] USB not working after suspend/resume-cycle
Hi there! Recently I got myself a usb keyboard for my freerunner, and it works quite nicely after putting the fr into host mode like described in the wiki. Well, except for one little thing: It only works if the freerunner has not been suspended before. If it has, usb host mode seems to be broken. With the testing kernel, I was able to fix that by rmmoding and modprobing the ohci_hcd module, but with earlier stable kernels, that module seems to be compiled into the kernel :( Any ideas how I can fix that without upgrading to a new kernel? Is there some special file in /sys/ or /proc/ which I can use to restart the usb subsystem? Or, if that isn't possible, how I can upgrade to a new kernel without breaking my current distribution (which is FDOM from October 2008)? Any help appreciated!
