Hi Phil,

you could use my patch  - see 
This would solve your problem with device family 28 (had the same problem).
For the other device with 7E you can use the other option which offers 
the patch - to use "direct accss" by specifying the whole OWFS path 
(also documented in the patch).

Or just use it as an inspiration :-)

Best regards,
