I directly connected to my Air USB 3.0 port without a hub and did 10 screen dumps. The xfer is much faster, and I do get all the data, and it is consistent and repeatable. However I cannot compare to the USB 2.0 screenshots because the screen image is different with the USB 3.0 high amp ports (battery is charging). I guess with plain 'ol low amp USB you cannot charge the Prime.

BTW on any USB port I always get the following error:

Code:


hpcalcs INFO: prime_recv_data: breaking because the expected size was reached (2)
hpcalcs INFO: prime_recv_data: shortening packet from 18774 to 18728
hpcalcs DEBUG: read_vtl_pkt: command matches returned data
hpcalcs INFO: calc_prime_r_recv_screen: embedded=1A computed=AAA
hpcalcs ERROR: calc_prime_r_recv_screen: CRC mismatch
hpcalcs INFO: hpcalcs_calc_recv_screen: recv_screen succeeded

But I always get the data, and it's clean. The number of CRC ERRORs is always just the one at the end.

Try my binaries. I'll upgrade to 10.9.1 around the 31st and retest.
