Problems detecting file-backed storage gadget on usb

[John Linn]

I am running Ubuntu 6.10 as a USB Host machine.  

 

I am plugging in an embedded device running open source linux 2.6.27
with the file-backed storage gadget running. I plug it into the USB port
of the Ubuntu machine and expect the host to add a new scsi device sd*
when it sees it but it never does.  Other mass storage devices seem to
work fine.

 

When plugging in the embedded device with file-backed storage gadget I
only get the following messages.

 

Sep 23 09:29:12 wolfgang-pc kernel: [21976600.100000] usb 5-5: new high
speed USB device using ehci_hcd and address 71

Sep 23 09:29:13 wolfgang-pc kernel: [21976600.644000] usb 5-5: new high
speed USB device using ehci_hcd and address 72

Sep 23 09:29:13 wolfgang-pc kernel: [21976601.188000] usb 5-5: new high
speed USB device using ehci_hcd and address 73

Sep 23 09:29:13 wolfgang-pc kernel: [21976601.324000] usb 5-5: new high
speed USB device using ehci_hcd and address 74

 

When I plug in other mass storage devices I get messages about the scsi
devices.

 

This works on a redhat machine so I'm thinking there's a configuration
issue or a bug somewhere?

 

Thanks,

John
