I upgraded from the 20.2 beta to stable. Things seem okay, except my ConvertX has disappeared.

Here's the relevant line from lsusb:
Bus 002 Device 003: ID 093b:a104 Plextor Corp.

I double-checked my loader script, which is executing the following:
fxload -t fx2 -D /proc/bus/usb/002/003 -I /lib/firmware/ezusb/hpi_PX-TV402U.hex

When I run that by hand with -vv, I get a return value of zero, and the following output:
Code:
microcontroller type: fx2
single stage:  load on-chip memory
open RAM hexfile image /lib/firmware/ezusb/hpi_PX-TV402U.hex

Ideas? The kernel is newer, and I rebuilt the wis-go7007-linux-0.9.8-patched drivers to match it.

gorecord complains as you'd expect- "Driver loaded but no GO7007".
