I can't receive 2 sysex dumps after each other without getting 10 garbage bytes between the 2 dumps.

Forgot to mention: it's odd that you always get exactly 10 bytes of repeated data. The header of a MIDIPacket is 10 bytes long (it's 8 bytes timestamp, 2 bytes length, then variable-length data), so perhaps the driver is doing some pointer math incorrectly at some point? Could just be a coincidence, but the fact is at least suggestive.

Do you get the 10 bytes of garbage all at once in a separate packet or packet list, or is it attached to a "good" packet or packet list? You may want to change your code to print out the timestamps and boundaries of packets/packet lists as well.
