    Ok:

    Before starting hotplug system:

    hciconfig -a show nothing
    root@gemini:~# lsusb

Bus 001 Device 001: ID 0000:0000 

After starting hotplug:

root@gemini:~# /etc/init.d/hotplug start
** can't synthesize input events - /proc/bus/input/devices missing
** can't synthesize pci hotplug events

    I use UHCI USB system.


    Well, now after the timeout problem:

    root@gemini:~# hciconfig -a
hci0:   Type: USB
        BD Address: 00:80:C8:50:F2:D5 ACL MTU: 377:10  SCO MTU: 16:0

0x1007
        Manufacturer: Broadcom Corporation (15)

    After this, if i try:

    root@gemini:~# hciconfig hci0 down

    root@gemini:~# hciconfig hci0 up 
    Can't init device hci0. Connection timed out(110)

root@gemini:~# hciconfig -a
hci0:   Type: USB
        BD Address: 00:80:C8:50:F2:D5 ACL MTU: 377:10  SCO MTU: 16:0
        DOWN
        RX bytes:8005 acl:84 sco:0 events:90 errors:0

        Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3
        Link policy: HOLD SNIFF PARK
        Link mode: ACCEPT MASTER
   

       I updated my kernel to 2.4.24 also yesterday, and the problem 
persists. So, i have 2 problems: The conn that fails after some seconds 
and the hci0 that does not come back after that.

Thanks again.
