hi thereI didn't set this bit because in my intel spec stands, that this bit doesn't have any effect on the controller but it could be used as a semaphore. After your hint i set this bit and it works. :o) Thanks
i'm working on the same project- usb support for one BIOS, so i'm writing in ASM.
i've got same errors sometimes when tried to send TD's with wron device-speed bit set. are you sure, your device isn't low-speed?
also- try to set "configured" bit in USBCMD
do you have all other FP with "terminated" bit set?Yes i had.
heh, i've just checked your port status register: PORT 0: 01 a5 : 0000110100101
as shown in UHCI design guide bit 8 set means low-speed device have been attached.I know that the device was an LowSpeedDevice but after 4 days of debugging i tried very thing (beside the "configured" bit :o( ) so i must have send a log where this bit wasn't set.
so in your TDs, addressed to this device
LowSpeed Device: 00 : 0
have to be set in "1"
Thanks.
