The change in vpo.c was
@@ -421,6 +421,7 @@
cpi->max_lun = 0;
cpi->initiator_id = VP0_INITIATOR;
cpi->bus_id = sim->bus_id;
+ cpi->base_transfer_speed = 3300;
strncpy(cpi->sim_vid, "FreeBSD", SIM_IDLEN);
strncpy(cpi->hba_vid, "Iomega", HBA_IDLEN);
strncpy(cpi->dev_name, sim->sim_name, DEV_IDLEN);
What about the call to
cam_sim_set_basexfer_speed(vpo->sim, 93/*kB/s*/);
should it be removed?
Second, the 3300 is quite different from the 93 kb/s. This looks a
cut&paste bogon. 93kb/s is more like perceived performance on ppbus.
Just asking because the dev/usb/umass driver needs updating as well
(iomega USB Zip drive driver).
