usb_host_lib example won't enumerate Launchpad Mk2

Postby mdroberts1243 » Tue Jun 06, 2023 7:07 pm

Hi,

I've been trying to use the usb_host_lib example with a Novation Launchpad Mk2 and it is always failing:

Code: Select all

I (829) DAEMON: Installing USB Host Library
V (829) intr_alloc: esp_intr_alloc_intrstatus (cpu 0): checking args
V (839) intr_alloc: esp_intr_alloc_intrstatus (cpu 0): Args okay. Resulting flags 0x802
D (849) intr_alloc: Connected src 48 to int 12 (cpu 0)
I (879) CLASS: Registering Client
I (879) CLASS: In while loop
I (879) CLASS: driver_obj.actions == 0
D (2479) HUB: Root port reset

E (2479) HUB: Bad transfer status 1: CHECK_SHORT_DEV_DESC
E (2479) HUB: Stage failed: CHECK_SHORT_DEV_DESC
D (2489) HUB: Stage done: CLEANUP_FAILED
The Launchpad stays in light show mode (not enumerated). Searching around I have tried to increase all the timers in menuconfig with no effect.

I have tried the same example with an Arturia Keystep and it seems to work fine:

The Launchpad works fine in regular use.

Any ideas on how I can get past this error?
