#1887 closed defect (wontfix)

adm5120 USB host controller not enabled, and not configurable.

Reported by: bifferos Owned by: developers
Priority: normal Milestone:
Component: packages Version:
Keywords: Cc:


According to target/linux/adm5120-2.6/config/default this should be compiled-in, but it doesn't seem to work. I would expect the message: "ADM5120 USB Host Controller Driver" on boot but it doesn't come up. Also, no log messages when inserting devices.

Here is a fairly feeble attempt to make the driver a module:

Unfortunately, it doesn't work:

  • Resolution set to wontfix
  • Status changed from new to closed

This is not the way we want it to act. The ADM5120 HCD should be built in the kernel and it detects whether the board supports USB or not (flash has_usb in adm5120_board). Now why it does not work currently, it is because the driver is broken and has been fully migrated to the Linux USB API.

OK. I was looking at the forum article
it says "USB has been rewritten but needs testing". This is presumably wrong. It can't be tested if it won't compile.
