If you have a pi and a pico and facing occasional USB connectivity issues (pico failing to enumerate etc), do two things:

1. upgrade RPI firmware (rpi-eeprom-update ....). This updates the USB controller firmware.
2. build your pico code with PICO_RP2040_USB_DEVICE_ENUMERATION_FIX=1 if you have a RP2B0 or B1 silicon.

These two changes fixed a lot of annoying issues for me.
