After a USB reset in the middle of a transfer MSC stayed in the data phase of the old command, so the retried command never completed. The host sends SET_CONFIGURATION again after every USB reset, so usb.SetupConfig now has an optional ResetHandler that is called then, and MSC uses it to go back to waiting for a CBW, the same as a Bulk-Only Reset.

I tested this on top of the updated #5808, and with a rebased #5794 on top of both. On a XIAO RP2350 with a flash backed drive and both On a XIAO nRF52840 Sense with #5794 on top, a RAM drive whose One thing I still want to look at. After an UNMAP that fails and times out, the next write gets a host transport error in 10 of 11 runs with this PR and in none of 3 runs without it. That UNMAP error path never sends a CSW on dev either, so I will look at both together. |

Stacked on #5808, which moves #5805 to a branch in this repo. Replaces #5807.
When a command takes longer than the host timeout, Linux recovers with a USB port reset. MSC was not told about the reset, so it stayed in the data phase of the old command and treated the retried CBW as data. The retried command never completed and the Linux SCSI error handler ended up blocked.
The host sends SET_CONFIGURATION again after every USB reset, and that is handled in the shared
usb.gofor all chips.usb.SetupConfiggets an optionalResetHandlerthat is called there. MSC uses it to go back to waiting for a CBW, the same state reset as a Bulk-Only Reset, and also clears its stall flags since the endpoints are reinitialized.Testing
On a Raspberry Pi Pico with a flash backed drive whose
ReadAtstalls once for 40 s, longer than the 30 s Linux SCSI timeout:ddhangs in the kernel until the board is unplugged.ddfinishes with the same data as a normal read.On dev without #5808 the same slow
ReadAtblocks the USB interrupt and the device drops off the bus.Also checked with both
-scheduler=tasksand-scheduler=cores: the drive mounts, a 300 KB file written over USB reads back the same after a remount and a reboot, andsrc/examples/usb-storagestill reads the same after ausbreset.src/examples/usb-storagebuilds for pico, xiao-rp2350, feather-nrf52840 and itsybitsy-m4.
