SubjectRe: HCI USB on USB 2.0: hci_usb_intr_rx_submit (works with USB 1.1)
From
Date

Marcel,

This was under 2.6.7, using ehci for USB 2.0 and uhci for 1.1.

Under 2.6.8.1 I get with USB 1.1:
usb 4-1.3: new full speed USB device using address 3
bcm203x_probe: Mini driver request failed
bcm203x: probe of 4-1.3:1.0 failed with error -5
usb 4-1.3: USB disconnect, address 3
usb 4-1.3: new full speed USB device using address 4

but USB 2.0 gives:
usb 1-3.4: new full speed USB device using address 6
ehci_hcd 0000:00:1d.7: qh f7d2d200 (#0) state 1
bcm203x_probe: Mini driver request failed
bcm203x: probe of 1-3.4:1.0 failed with error -5
usb 1-3.4: bulk timeout on ep1in
usb 1-3.4: usbfs: USBDEVFS_BULK failed ep 0x81 len 10 ret -110
usb 1-3.4: USB disconnect, address 6
usb 1-3.4: new full speed USB device using address 7
ehci_hcd 0000:00:1d.7: qh f7d2d280 (#0) state 1
hci_usb_intr_rx_submit: hci0 intr rx submit failed urb c1ad1994 err -28

If I try to do 'hciconfig hci0 up' when connected to USB 2.0 I also get
a 'hci_usb_intr_rx_submit: hci0 intr rx submit failed urb f7e22814 err
-28'.

Thanks,

PS Sorry for the late reply, I just returned from vacation.

Raf.
