I'm tring to use the usb 2.0 ports of mu ibook G4 but I've some problems...
I've build into the kernel the module:
Code:
ehci-hcd

but when I my usbmouse and my usb-pen (that supports usb 2.0) doesn't work.

The only way to get them working is to build only the module
Code:
ohci-hcd


How can I get usb 2.0 working :?:

PS: I'm using kernel 2.6.8

build both: ohci-hcd dispatches USB2 devices to ehci-hcd. (iirc)

Ok I've done this but usb-pen still works using usb 1.1 drivers:
Here's the log of kernel's events

put in usb mouse
Code:

Oct 20 21:15:45 [kernel] usb 3-1: USB disconnect, address 2
Oct 20 21:15:46 [kernel] usbcore: deregistering driver usbmouse
Oct 20 21:15:51 [kernel] ohci_hcd 0001:01:1b.0: wakeup
Oct 20 21:15:51 [kernel] usb 3-1: new low speed USB device using address 3
Oct 20 21:15:52 [kernel] input: USB HID v1.10 Mouse [Logitech USB Receiver] on usb-0001:01:1b.0-1
Oct 20 21:16:30 [kernel] usb 3-1: USB disconnect, address 3

it works

put it one usb-key 2.0
Code:

Oct 20 21:16:34 [kernel] usb 1-1: new high speed USB device using address 4
Oct 20 21:16:34 [kernel] hub 1-1:1.0: USB hub found
Oct 20 21:16:34 [kernel] hub 1-1:1.0: 1 port detected
Oct 20 21:16:34 [kernel] usb 1-1.1: new high speed USB device using address 5
Oct 20 21:16:35 [kernel] Initializing USB Mass Storage driver...
Oct 20 21:16:35 [kernel] scsi0 : SCSI emulation for USB Mass Storage devices
Oct 20 21:16:35 [kernel]   Vendor: Sony      Model: Storage Media     Rev: 1.00
Oct 20 21:16:35 [kernel] USB Mass Storage device found at 5
Oct 20 21:16:35 [kernel] SCSI device sda: 256000 512-byte hdwr sectors (131 MB)
Oct 20 21:16:35 [kernel] sda: Write Protect is off
Oct 20 21:17:06 [kernel] usb 1-1: USB disconnect, address 4

The key works (/dev/sda1 is created) but it works using usb 1.1 drivers

Another usb-pen 2.0
Code:

Oct 20 21:18:36 [kernel] usb 1-1: new high speed USB device using address 6
Oct 20 21:18:36 [kernel] scsi1 : SCSI emulation for USB Mass Storage devices
Oct 20 21:18:36 [kernel]   Vendor: VMAX      Model: 128MB             Rev: 2.00
Oct 20 21:18:36 [kernel] sda: Unit Not Ready, sense:
Oct 20 21:18:36 [kernel] SCSI device sda: 256000 512-byte hdwr sectors (131 MB)
Oct 20 21:18:36 [kernel] sda: Write Protect is off
Oct 20 21:18:36 [kernel] USB Mass Storage device found at 6

In this case /dev/sda isn't created. The pen doesn't work under linux, but using mac os there's no problem.
I think this key doesn't accept usb 1.1 drivers (on a pc with usb 1.1 it didn't work)
