it include the 101b: Get partial object and 95c1: Get Partial Object (64bit Offset), but i cannot get the data by the both operations.

[Marcus Meissner]

is there any further debugoutput?
export LIBMTP_DEBUG=255

and debug output might be printed to stderr?

[Marcus Meissner]

For opcode 95c1 it gets error 2005 aka "OperationNotSupported".

which is weird, it should not report the opcode if it does not support it.

DOes it work in non-ADB mode?

[Anonymous]

I try to use opcode 0x101B to get the partial object，it is OK.
