Hello!
USB stopped working on my Blue&White PowerMAC after upgrading to Linux
2.6.5-rc2. 2.6.5-rc1 is OK. The symptoms are that the list of the
devices as shown by lsusb doesn't change when devices are connected or
disconnected. It shows the devices present at startup. The interrupt
count for the ohci controller doesn't change.
The relevant kernel messages with 2.6.5-rc1 are:
ohci_hcd: 2004 Feb 02 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI)
ohci_hcd: block sizes: ed 64 td 64
ohci_hcd 0000:01:06.0: OHCI Host Controller
ohci_hcd 0000:01:06.0: irq 28, pci mem f2041000

Latency: 16, Cache Line Size: 0x08 (32 bytes)
Interrupt: pin A routed to IRQ 28
Region 0: Memory at 80880000 (32-bit, non-prefetchable) [size=4K]
Compiling OHCI support as module doesn't help. The module cannot be
unloaded despite use count 0.
I see massive USB changes between 2.6.5-rc1 and 2.6.5-rc2, and I cannot
split them further without breaking compilation.
