Issues

Transfer to endpoint failed

kernel: [67839.403339] Transfer to device 6 endpoint 0x1 frame 2026 failed - FIQ reported NYET. Data may have been lost.

USB Device 6 turns out to be the UPS: 

# lsusb
Bus 001 Device 006: ID 0764:0501 Cyber Power System, Inc. CP1500 AVR UPS

Seems to be an intermittent issue as able to still get UPS device status with apcaccess.

The UPS is connected to a RaspberryPi and Google searches seem to show this issue appears to be isolated to the Raspberry Pi.
