Hi!
I am planning to buy mp3 player with CF card, which uses USB with
Linux. For example Mello, which is on market in our contry. I tryed
to found informations about it, but I found only 3 letters, which
wrotes about problems. These problems still persist? There are parts
from Donovan Craigs e-mail (11/24/2002):

And this is from log file:____

I think, Cls=08 is OK, but Sub=06 according protocol.h is using
US_SC_SCS (transparent) proctocol. It should be US_SC_8070 removable
media, isn't it?
What you think, about adding this to unusual_devs.h:
UNUSUAL_DEV( 0x0547, 0x2810, 0x0001, 0x0001,
"Mello",
"MP3 Player",
US_SC_8070, US_PR_CB, NULL,0 ),
What you think, it could help, or better forget it? Better idea?
Is there anybody, who could share experiences with Mello?
TIA
