Hello, I've got a custom board that I'm trying to verify that USB mass storage is functional.

 

I'm running kernel 3.0.35 (using LTIB).

 

When I plug in the USB flash drive I see the following in the dmesg output:

 

 

fsl-ehci fsl-ehci.1: GetStatus port:1 status 10001803 8  ACK POWER sig=j CSC CONNECT

hub 2-0:1.0: port 1: status 0101 change 0001

hub 2-0:1.0: state 7 ports 1 chg 0002 evt 0000

hub 2-0:1.0: port 1, status 0101, change 0000, 12 Mb/s

usb 2-1: new high speed USB device number 3 using fsl-ehci

fsl-ehci fsl-ehci.1: port 1 high speed

fsl-ehci fsl-ehci.1: GetStatus port:1 status 18001205 12  ACK POWER sig=se0 LPM PE CONNECT

usb 2-1: default language 0x0409

usb 2-1: udev 3, busnum 2, minor = 130

usb 2-1: New USB device found, idVendor=090c, idProduct=1000

usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3

usb 2-1: SerialNumber: 12031100001463

usb 2-1: usb_probe_device

usb 2-1: configuration #1 chosen from 1 choice

usb 2-1: adding 2-1:1.0 (config #1, interface 0)

hub 2-0:1.0: state 7 ports 1 chg 0000 evt 0002

 

looking up that vendor id and product id, it matches that of a Flash Drive, so it looks like the device is detected.  However, I cannot find a device like /dev/sda, or /dev/sdb, etc...My question is does kernel 3.0.35 on the i.MX6SoloLite support usb mass storage?  If so, then I must have other issues.
