No so easy to tell.
There are some debugging sysctl which you can try to tune/increase:
hw.usb2.pr_recovery_delay: 250
hw.usb2.ss_delay: 0
hw.usb2.ehci.no_hs: 0
Try double the values until it works reliably.
The logs don't tell me so much except that one of the control transactions
fail. Maybe you can dump the descriptors of your device?
usbconfig -u xxx -a yyy dump_device_desc dump_curr_config_desc
--HPS
