Hi, Low Speed devices (Mouse) does not work on the root hub. They would require another clock-rate. They may work with an external HUB.
Devices I use include: 4 port HUB (don't know the brand), Billiton System USB10/100 Ethernet USB-Ethernet (pegasus.c patched 2.4.2pre6 may include the right patch), Sandisk SDDR31 Image Mate (Compactflash Reader) (USB Storage of 2.4.2). Real transfer (Bulk transfer) will need patches of m8xxhci other than patch1,2. Board: TQM850L/STK850L with MPC850DEB-50MHz Sys/48MHZ Clock4 Timer1 for SOF Philips Tranceiver/Hardware Patch!!!! With patch 1 and without Hardware Patch and a HUB I get: ... m8xxhci: device found! m8xxhci_connect_device() m8xxhci_alloc_dev(usb_dev=c0f91600) hub.c: USB hub found hub.c: 4 ports detected rx err sc (status 0x1c54) m8xxhci: device lost m8xxhci_disconnect_device() hp->root_hub c0ff7560, hp->root_hub->usb c0f91600 usb.c: USB disconnect on device 1 unlink_urb(urb=c0f92910,qtype=1) status -115 unlink_urb(urb=c0f92910) done m8xxhci_free_dev(usb_dev=c0f91600) m8xxhci_free_dev(dev=c0f91600) done m8xxhci: device found! m8xxhci_connect_device() m8xxhci_alloc_dev(usb_dev=c0f91600) complete urb c0f92890, actual_length 0, status -1 unlink_urb(urb=c0f92890,qtype=2) status -110 unlink_urb(urb=c0f92890) done complete urb c0f92890, actual_length 0, status -1 unlink_urb(urb=c0f92890,qtype=2) status -110 unlink_urb(urb=c0f92890) done hub.c: USB hub found hub.c: 4 ports detected INIT: version 2.77 booting rx err sc (status 0x1c54) ---------- with Hardware Patch and Patch 1 I get: ... m8xxhci: device found! m8xxhci_connect_device() m8xxhci_alloc_dev(usb_dev=c0f91600) hub.c: USB hub found hub.c: 4 ports detected INIT: version 2.77 booting INIT: Entering runlevel: 3 sh-2.03# hope that helps - Roman > Hi, > > I managed to get the m8xxhci with the TIMER1 patch to sort of work with > my board. > I.e. the SOF seem to be genrated normally and there seem to be some > traffic on > the usb bus when I plug in keyspan_pda USB device.
