USB webcam device not published by usb_raw

[mmu_man]

My webcam doesn't get published by usb_raw in Haiku. It seems the stack doesn't like it:

KERN: usb_ehci: pipe change 0 for pipe 0x90b20480
KERN: usb_ehci: pipe change 0 for pipe 0x90b20500
KERN: usb_uhci: no devices found
...
KERN: USB BusManager: error while setting device address

...
KERN: USB Hub 1: port 2 disabled

KERN: USB BusManager: error while setting device address
KERN: USB Hub 1: port 2 enabled
KERN: Last message repeated 2 times.
KERN: USB BusManager: error while setting device address
KERN: USB Hub 1: port 2 enabled
KERN: Last message repeated 2 times.

Tried to enable DEBUG on usb but it doesn't seem to print much more...

Now this is pretty severe as the addressing is the very first step in handling a device. It is done even before getting a device descriptor or anything. It's possible that the device times out somehow then you could try playing around with the delay defines in "src/add-ons/kernel/bus_managers/usb/usbspec_p.h". They are generally larger than those specified in the USB specs, maybe some of them are too long for the device at hand.

Could you please also get and post some infos about the device to see if it has some known specifics.

syslog for usb webcam plugged in with ehci

[mmu_man]

I removed ohci, fixed ehci to not give up port ownership for slow devices, it seems to go further, but still gives an error. See attached syslog.

Now I see it: this is a USB 1.1 device and you are stuck with OHCI. Sorry, but there is no other "fix" than to implement OHCI in this case. It is not possible for EHCI to communicate with these devices. If you simply force keeping the ownership you at most risk damaging the device, but you will certainly not get it working. EHCI uses a different protocol which is incompatible with the one of older devices. I will close this bug as a duplicate, as bug #1044 already covers this.

Ok is that part of SoC at least or do I have to do it ? :D
