0. Есть линукc 2.4.27, sarge и usb сканер epson perfection 1270.

1. Проблема: ядро не видит сканер. Кстати, сканер поддерживается sane

2. Должно быть что--то вроде Vendor=0x04b8 ProdID=0x0120 Product=Espon scanner. Ан нет. :-(
$ cat /proc/bus/usb/devices
T:  Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=  1 Spd=12  MxCh= 2
B:  Alloc=  0/900 us ( 0%), #Int=  0, #Iso=  0
D:  Ver= 1.00 Cls=09(hub  ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=0000 ProdID=0000 Rev= 0.00
S:  Product=USB UHCI Root Hub
S:  SerialNumber=e400
C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr=  0mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=hub
E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=255ms

3. Естественно, что sane-find-scanner ничего не находит.
$ sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a SCSI driver for your SCSI adapter.
  # Also you need support for SCSI Generic (sg) in your operating system.
  # If using Linux, try "modprobe sg".

  # No USB scanners found. If you expected something different, make sure that
  # you have loaded a driver for your USB host controller and have installed a
  # kernel scanner module.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

  # You may want to run this program as root to find all devices. Once you
  # found the scanner devices, be sure to adjust access permissions as
  # necessary.

4. Хотя из вывода dmesg вроде бы следует что сканер опознан.

5. вроде бы сканер найден
$ cat /proc/bus/usb/drivers
         usbdevfs
         hub
48- 63: usbscanner

6. и модули есть нужные
# lsmod
....
scanner                10176   0
usb-uhci               19504   0  (unused)
usbcore                52268   1  [scanner usb-uhci]

7. кстати в /etc/modules.conf руками добавлена нужная информация.
$ tail /etc/modules.conf
options scanner vendor=0x04b8 product=0x0120

8. сам usb контроллер система видит

$ lspci
...
0000:00:07.2 USB Controller: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller (rev 11)

$ lsusb

9. Помогите люди добрые. Так не хочется маздаем машинку марать из--за одной несчастной железки.
