Hi Larry.  I wasn't clear enough.  I'm not using the TS7390 in this process.

When I put the MicroSD card in the USB reader attached to my PC running Ubuntu, 
not on the TS7390, it is recognised as a device, and /dev/sdb is created.  (sda 
is the real hard disk).  But no partitions are recognised, and 'parted 
/dev/sdb' give an error No Medium in Device.

So it is recognising the USB device as a removable SCSI device but claims there 
is no 'disk' in the device, I think.

But if I put in a SD card, it is recognised and devices corresponding to the 
partitions are created in addition to the main device.  Ie, /dev/sdb1 and 
/dev/sdb2 as partitions in addition to /dev/sdb.

I have tried spiflash2sd command which claims to work and to be writing to the 
MicroSD card.

So at this stage it looks more likely that the USB reader isn't correctly 
mounting (?) the MicroSD card although it works for normal SD card.

I have ordered the development microSD card which comes with a reader from 
Technologic; probably what I should have done in the first place.  I'll just 
have to be patient as it wings its way over the Atlantic.

Other niggles:

1) Telnetd is running but does not permit login; gives 'connection refused'.

2) Cannot mount NFS file system: get 'protocol not supported' although the 
identical mount command from a TS7250 running 2.4 kernel and busybox works 
perfectly.

3) I can't find a power supply unit that has a standard USB B connector on it - 
the Ipod ones use mini-B (or is it micro-B?)
