Hi Clemens,

Thanks for the information. The report from lsusb indicated that these
values:

    wMaxPacketSize 0x0020 1x 32 bytes

are the same for the MidiSport and the UA25. However, there's a lot of
information from that report. Is there any other particularly relevant
data I should gather from lsusb ?

Best,

dp
