Sorry for the confusion, after a format of the device I no longer see
the error a803 message. Just the other "call to
ptp_mtp_getobjectpropssupported() failed." message.

Error sending file "/tmp/gnomad-z2lCHP/01 Seguir Siendo.mp3" to MTP device!
Error 2: PTP Layer error 02fe: LIBMTP_Get_Filelisting_With_Callback():
call to ptp_mtp_getobjectpropssupported() failed.
Error 2: (Look this up in ptp.h for an explanation.)
Error 2: PTP Layer error 2002: add_object_to_cache(): couldn't add
object to cache
Error 2: (Look this up in ptp.h for an explanation.)
Error 1: LIBMTP_Send_File_From_File_Descriptor(): Could not retrieve
updated metadata.
Error 1: LIBMTP_Send_Track_From_File_Descriptor(): subcall to
LIBMTP_Send_File_From_File_Descriptor failed.

This didn't help either

I'll make a usb trace for you - give me a moment to put it together! :)
