USB Host Mass Storage Device

[BabumonGopi]

            Any working program for Mass Storage Device working with pico-sdk ? I had tried to connect with TinyUSB, but it will not working for pico. The following error is coming.

assertion "ep" failed: file "/Users/babumongopi/r-pi/pico-sdk/lib/tinyusb/src/portable/raspberrypi/rp2040/hcd_rp2040.c", line 492, function: hcd_edpt_xfer

Any solution ?

The best examples are in tinyusb library i think. Look up for lun msc code there. That example works perfectly.

bulk endpoint for host on rp2040 is not supported yet. Please wait until it is implemented

[BabumonGopi]

Is it the issue of RP2040 microcontroller itself or TinyUSB library ?

there is no issue with either rp2040 or TinyUSB. There is only issue with time or lack of it.

Bumping to 1.4.0 to review when we update TinyUSB

[BabumonGopi]

Any update ?

@liamfraser can you move this into 1.5.0 if it is fixed with latest TinyUSB
