Pico Not Discoverable in WSL2 #5021
Description
I'm trying to setup running the blinky example on the Raspberry Pi Pico under WSL2, I am able to get the device into BOOTSEL mode, I can see it recognized as a USB device, but flashing fails to find it and it isn't mountable as a device.
I'm using usbipd to share the device from windows to WSL2 (Ubuntu). I am able to successfully flash the device by building the .uf2 using tinygo build and then copying it to the device on the windows side. (i.e. the device is fine).
$ tinygo flash -target=pico ./blinky
failed to flash /tmp/tinygo863331782/main.uf2: unable to locate any volume: [RPI-RP2]$ lsusb
