It is fully supported. What build id is this? I know that the Rev equals the build id, but I always forget how to convert it. > ># ps -aux > > PID Uid Stat Command > > 1 0 S init noinitrd > > 2 0 S [keventd] > > 3 0 S [ksoftirqd_CPU0] > > 4 0 S [kswapd] > > 5 0 S [bdflush] > > 6 0 S [kupdated] > > 7 0 S [mtdblockd] > > 15 0 S /usr/sbin/dnsmasq > > 24 0 S /usr/sbin/diag > > 25 0 S /bin/sh > > 35 0 S [khubd] > > 63 0 S [krfcommd] > > 77 0 S hcid: processing events > > 80 0 S sdpd > > 104 0 S hcid: processing events > > 108 0 S hcid: hci0 init > > 111 0 S /usr/sbin/hidd --server > > 124 0 R ps -aux Make sure only one hcid is running at a time. > The problem is that hciconfig doesn't come up: > ># hciconfig > >hci0: Type: USB > > BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0 > > DOWN > > RX bytes:20 acl:0 sco:0 events:2 errors:0 > > TX bytes:9 acl:0 sco:0 commands:3 errors:0 > > When we're trying to wake it up, it failed on timeout: > ># hciconfig hci0 up > >Can't init device hci0: Connection timed out (145) > We received the same timeout reply for version, revision and commands > requests. > We received the following reply for features request (# hciconfig hci0 > features) > hci0: Type: USB > BD Address: 00:00:00:00:00:00 ACL MTU: 192:8 SCO MTU: 64:8 > Features: 0xff 0xff 0x0f 0x00 0x00 0x00 0x00 0x00 > <3-slot packets> <5-slot packets> offset> > mode> > packets> >

It's strange. You need to have a dongle that actually supports HID proxy.

Move to a 2.6 kernel, because I think this is a bug inside the USB subsystem. However if you don't need SCO support, you might wanna disable the ISOC transfers (SCO support) of the hci_usb driver.
