 I've managed to up them until the following values, rebooting after each =
 change.
 
 hw.usb.timings.port_reset_delay: 800
 hw.usb.timings.port_root_reset_delay: 4000
 hw.usb.timings.port_reset_recovery: 4000
 hw.usb.timings.port_powerup_delay: 300
 hw.usb.timings.port_resume_delay: 640
 hw.usb.timings.set_address_settle: 160
 hw.usb.timings.resume_delay: 4000
 hw.usb.timings.resume_wait: 800
 hw.usb.timings.resume_recovery: 800
 hw.usb.timings.extra_power_up_time: 320
 
 The problem still persists, although the dmesg flood rate is =
 considerably smaller now. I guess this is to be expected.
 
 Unfortunately, this USB device is allocated by request for =
 troubleshooting purposes, and I cannot have access to it for more than a =
 few hours at a time.=
