Yo tenía un problema similar con un pen drive de 256 MB hasta que conseguí un parche para el módulo usb_storage: ===== drivers/usb/storage/scsiglue.c 1.74 vs edited ===== --- 1.74/drivers/usb/storage/scsiglue.c Sat Apr 24 22:25:50 2004 +++ edited/drivers/usb/storage/scsiglue.c Tue May 18 10:02:17 2004 @@ -48,12 +48,15 @@ #include "usb.h" #include "debug.h" #include "transport.h" +#include "protocol.h" #include #include #include #include +#define SKIP_MODE_SENSE_PAGE_3F 1 + /*********************************************************************** * Host functions @@ -68,10 +71,13 @@ { /* * Set default bflags.

en SuSE 9.1 cuando pincho un pendrive USB de 128 megas puedo ver su contenido en /media/usb-storage-xxxxxx. Pero cuando pincho un Creative MuVo de 128 megas que, en SuSE 9.0 me lo reconoce como un disco fat, me sale el siguiente log en /var/log/messages Dec 8 02:04:40 linux kernel: usb 3-1: new full speed USB device using address 9 Dec 8 02:04:40 linux kernel: usb 3-1: Product: NOMAD MuVo Dec 8 02:04:40 linux kernel: usb 3-1: Manufacturer: Creative Tech Dec 8 02:04:40 linux kernel: usb 3-1: SerialNumber: 000000000000 Dec 8 02:04:40 linux /etc/hotplug/usb.agent[7149]: need a device for this command Dec 8 02:04:40 linux kernel: scsi3 : SCSI emulation for USB Mass Storage devices Dec 8 02:04:40 linux kernel: Vendor: CREATIVE Model: NOMAD_MUVO Rev: 0001 Dec 8 02:04:40 linux kernel: Type: Direct-Access ANSI SCSI revision: 02 Dec 8 02:04:40 linux kernel: SCSI device sda: 256001 512-byte hdwr sectors (131 MB) Dec 8 02:04:40 linux kernel: sda: assuming Write Enabled Dec 8 02:04:40 linux kernel: sda: assuming drive cache: write through Dec 8 02:04:40 linux /etc/hotplug/block.agent[7199]: try 1 while waiting for /block/sda's bus_id 3:0:0:0 Dec 8 02:04:40 linux kernel: sda:end_request: I/O error, dev sda, sector 256000 Dec 8 02:04:40 linux kernel: Buffer I/O error on device sda, logical block 256000 Dec 8 02:04:41 linux /etc/hotplug/block.agent[7199]: try 2 while waiting for /block/sda's bus_id 3:0:0:0 Dec 8 02:04:42 linux /etc/hotplug/block.agent[7199]: try 3 while waiting for /block/sda's bus_id 3:0:0:0 Dec 8 02:04:43 linux /etc/hotplug/block.agent[7199]: try 4 while waiting for /block/sda's bus_id 3:0:0:0 Dec 8 02:04:44 linux /etc/hotplug/block.agent[7199]: try 5 while waiting for /block/sda's bus_id 3:0:0:0 Dec 8 02:04:45 linux /etc/hotplug/block.agent[7199]: new block device /block/sda y no monta el /media/usb-storage-xxxxxx ¿teneis idea de la solución?
