Hi,
I've made my usb mp3 player to work with linux 2.6.15, just by adding it to
unusual_devs.h.
It is mp3 player 'ACME Sound MP3 Player for SD/MMC card' Model: EM120X. I
think it's based on Samsung's chipset (lsusb shows vendor 'Samsung...'). so
there could be more similar devices.
In case it would be useful for somebody, here's the info about device as
described in unusual_devs.h comment:
