LIBUSB_ERROR_PIPE = -9, LIBUSB_ERROR_PIPE if the control request was not supported by the device
You seem to be the first one to encounter this issue so I'm inclined to believe it's something to do with your FX2 board or specific battery pack. Does it recover if you remove and reattach power to (or just reset) the battery controller while keeping the FX2 powered? What happens when you try a write scan? (smbusb_scan -w 0x16)

smbusb_scan -a only seems to work until it finds my controller (bq8030), after that it always comes back with ERROR -9. First scan:
`------------------------------------ smbusb_scan
SMBusb Firmware Version: 1.0.1 Scanning for addresses.. Scan range: 00 - ff Skipping: a0 a1
[16] ACK [17] ACK [19] ERROR: -9 [1a] ERROR: -9 [1b] ERROR: -9 [1c] ERROR: -9 [1d] ERROR: -9 [1e] ERROR: -9 [1f] ERROR: -9 `
Starting another scan after that:
`------------------------------------ smbusb_scan
SMBusb Firmware Version: 1.0.1 Scanning for addresses.. Scan range: 00 - ff Skipping: a0 a1
[0] ERROR: -9 [1] ERROR: -9 [2] ERROR: -9 [3] ERROR: -9 [4] ERROR: -9 [5] ERROR: -9 [6] ERROR: -9 [7] ERROR: -9 [8] ERROR: -9 [9] ERROR: -9 [a] ERROR: -9 [b] ERROR: -9 [c] ERROR: -9 [d] ERROR: -9 [e] ERROR: -9 [f] ERROR: -9 [10] ERROR: -9 [11] ERROR: -9 [12] ERROR: -9 [13] ERROR: -9 [14] ERROR: -9 [15] ERROR: -9 [16] ERROR: -9 [17] ERROR: -9 `
Every time I plug in the FX2 it will work exactly once. I tested it on my laptop running Manjaro and on a Raspberry Pi 2.
