[linux] USB kluc a prechod na jadro 2.6.10

[Lubomir Host]

Caute,

prave som zistil jednu zaujimavu vec. Ak pripojim cez USB kabel
digitalny fotak, tak sa mi vytvori normalne zariadenie /dev/sda1 aj
mozem skopirovat fotky. Vid dmesg:

---------------------------------%<---------------------------------
usb 2-1: new full speed USB device using uhci_hcd and address 2
scsi0 : SCSI emulation for USB Mass Storage devices
usb-storage: device found at 2
usb-storage: waiting for device to settle before scanning
  Vendor: MINOLTA   Model: DiMAGE G400       Rev: 1.00
  Type:   Direct-Access                      ANSI SCSI revision: 00
usb-storage: device scan complete
SCSI device sda: 250880 512-byte hdwr sectors (128 MB)
sda: Write Protect is off
sda: Mode Sense: bc 00 00 bc
sda: assuming drive cache: write through
SCSI device sda: 250880 512-byte hdwr sectors (128 MB)
sda: Write Protect is off
sda: Mode Sense: bc 00 00 bc
sda: assuming drive cache: write through
 sda: sda1
Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0
usb 2-1: USB disconnect, address 2
---------------------------------%<---------------------------------

Ak vsak pripojim do toho isteho portu USB kluc, deje sa toto:

-------------------------------%<-------------------------------
usb 2-1: USB disconnect, address 2
usb 4-3: new high speed USB device using ehci_hcd and address 3
usb 4-3: khubd timed out on ep0in
usb 4-3: khubd timed out on ep0out
usb 4-3: khubd timed out on ep0out
usb 4-3: device not accepting address 3, error -110
usb 4-3: new high speed USB device using ehci_hcd and address 4
usb 4-3: khubd timed out on ep0in
usb 4-3: khubd timed out on ep0out
usb 4-3: khubd timed out on ep0out
usb 4-3: device not accepting address 4, error -110
-------------------------------%<-------------------------------

Kde moze byt zadrhel? Bezi uz niekto na jadre 2.6.10 a pouziva USB kluc?
Moze niekto poslat konfigurak jadra?

Diik, rajo
