Vipers at a2, a6 and c20 are OK.
USB info
The viper kernel has a patch to use an assembler delay function for the isp116x, and not the kernel ndelay() function. Don't think this is related though.
The driver code that sets up the interrupt:
| Code Block |
|---|
if (board->int_act_high)
val |= HCHWCFG_INT_POL;
if (board->int_edge_triggered)
val |= HCHWCFG_INT_TRIGGER;
|
The current driver is using the defaults: level triggered, active low.
