[8-STABLE] ohci / uhub / umass - only works once.
Hi,
I have a strange problem: I have a device with a card reader (and
harddisk slot), obviously containing it's own USB hub, too. I use it as
SD card reader.
I attach the SD card, switch the device on. hub and SD card slot show up
in dmesg, I can use them.
After unmounting I switch of the device, umass and hub get detached
fine.
I I switch on the device the next time it doesn't show up at all
anymore, as if nothing happens on the USB port. On my old machine (UHCI
instead of OHCI) everything worked like expected, the device also works
on other operating systems/machines as expected.
Detraching and reattaching of other devices (like webcam) works just
normal. I don't have a card reader to check with a device without own
hub, but I think I've seen the same behaviour (doesn't work after
detach) with a USB stick, will check that if needed.
