Which one? The MX28 p-o-s? Skimming through it's sources, I already used two
puking bags, more to be filled tho.

MX28 bootrom does this. I barely have words for the flubs I unveiled so far in
it.
Greg, do you please have any solution for this problem? Basically, the probe of
hid fails on the fact that the HID_GLOBAL_ITEM_TAG_REPORT_SIZE is 128, while
right now it's capped at 96.
Shall I submit a patch that increases it to 128 maybe? Please advise. Thanks!
