Thank you, Alan, First, I plug the card reader to a regular Linux system, the dmesg command prints the following text: hub.c: new USB device 00:07.2-1, assigned address 2 usb.c: USB device 2 (vend/prod 0x58f/0x6366) is not claimed by any active driver. Initializing USB Mass Storage driver... usb.c: registered new driver usb-storage scsi1 : SCSI emulation for USB Mass Storage devices Vendor: Multi Model: Flash Reader Rev: 1.00 Type: Direct-Access ANSI SCSI revision: 02 Attached scsi removable disk sdc at scsi1, channel 0, id 0, lun 0 SCSI device sdc: 128512 512-byte hdwr sectors (66 MB) usb-uhci.c: interrupt, status 3, frame# 964 sdc: Write Protect is off sdc: sdc1 WARNING: USB Mass Storage data integrity not assured USB Mass Storage device found at 2 USB Mass Storage support registered.
It means the card reader is okay. Second, I mounted the usbfs to /proc/bus/usb with "mount -t usbfs none /proc/bus/usb", then the /proc/bus/usb has two entries: $ ls -l /proc/bus/usb dr-xr-xr-x 2 0 0 0 Jan 1 1970 001 -r--r--r-- 1 0 0 0 Jun 1 10:46 devices /proc/bus/usb/devices has the following content: $ 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= 1.10 Cls=09(hub ) Sub=00 Prot=00 MxPS=64 #Cfgs= 1 P: Vendor=0000 ProdID=0000 Rev= 2.06 S: Manufacturer=Linux 2.6.22-uc0 ohci_hcd S: Product=W90N74X OHCI S: SerialNumber=W90N74x C:* #Ifs= 1 Cfg#= 1 Atr=e0 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.)

First, make sure /proc/bus/usb is mounted: mount -t usbfs none /proc/bus/usb Second, try plugging the card reader into a regular Linux system to make sure it is okay. Third, try plugging a different USB device (like a flash memory) into your machine, instead of the card reader. The error message means that Linux didn't receive a status reply from the card reader after sending it a READ CAPACITY command. Either the card reader didn't send a status reply or else the host controller driver didn't detect the reply.
