(57) It's fine you solved your problem, but... I currently have a similar dongle "Souyo (r) Bluetooth (tm)", that doesn't work with either usb2 or integrated usb 1.1 (i use no hub). # hciconfig -a hci0: Type: USB BD Address: 11:11:11:11:11:11 ACL MTU: 678:8 SCO MTU: 64:8 UP RUNNING PSCAN RX bytes:1224 acl:0 sco:0 events:28 errors:0 TX bytes:608 acl:0 sco:0 commands:28 errors:0 Features: 0xbf 0xfe 0x8d 0x78 0x08 0x18 0x00 0x00 Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3 Link policy: RSWITCH HOLD SNIFF PARK Link mode: SLAVE ACCEPT Name: 'littletux-1' Can't read class of device on hci0: Connection timed out (110) # lsusb Bus 003 Device 004: ID 1131:1001 Integrated System Solution Corp. KY-BT100 Bluetooth Adapter Tried without force_scofix, in case of (maybe needed only for the other dongle). There is an other quirk needed (reset), so I haven't tried btusb module.

I wouldn't recommend these old dongles. Mailing-list readers should get a bluetooth 2.0 or more dongle, it's the same price as a 1.2 one.
