2026-07-03dcd(samd): implement iso alloc/activate (were stubs returning false)hathach
dcd_edpt_iso_alloc/activate were unimplemented stubs. Since samd is an ISO_ALLOC port, the stack routes ISO endpoints through them, so every ISO endpoint open failed: SET_CONFIGURATION with an ISO endpoint returned -EPIPE (can't set config) and audio SET_INTERFACE(alt=1) stalled at usbd_edpt_iso_activate(). This was misdiagnosed as a samd51 hardware ISO limitation; it is not. Implement them mirroring dcd_edpt_open()'s per-direction setup: iso_alloc fixes the endpoint bank SIZE bucket for the largest packet size (persists across altsettings); iso_activate sets EPTYPE=ISO, clears stall + data toggle, enables the transfer-complete interrupt. metro_m4_express now passes the full usbtest battery 30/30 (was: SET_CONFIG failed), including ISO 15/16/22/23.

Allow more endpoint packet sizes for SAMD
2022-06-27samd: Fix a lock-up situation at high traffic.robert-hh
This PR fixes a transmit lock-up, which happens, when data is received and sent at the sime time at moderate to high speeds, like code which just echoes incoming data. In my case, an issue was reported here: https://github.com/micropython/micropython/issues/8521
2022-06-17Allow more endpoint packet sizes for SAMDmaddyaby
Tested on SAMD51 - we can allow more packet sizes by checking that the set size value is greater than the requested packet size instead of exactly the same.
2022-06-16Stub out dcd_edpt_close for samdmaddyaby
Not having this prevents the device from finishing the mounting process. Tested on a SAMD51 and didn't seem to need to actually do anything in the close function.
