dmesg
[ 86.174022] usb 2-2-port1: attempt power cycle
[ 88.154102] usb 2-2.1: new full-speed USB device number 10 using uhci_hcd
[ 88.180832] usb 2-2.1: device descriptor read/8, error 2

Can you interact via screen or what ever serial terminal you use

No, it just kept trying to enumerate continually.
Solved it by connecting it via a USB hub instead of directly to the USB port.

Well it took quite a long time to resolve this and eliminate the need for a USB2 Hub.
When plugging in the Pyboard the pyboard was listed in the ESXI VM's devices as a USB device by Vendor Name and PID and was never enumerated by the VM O/S.
After applying this fix, the device is correctly listed as a "MicroPython Pyboard Virtual Comm Port in FS Mode"
But this problem
only affects VMWARE/ESXI 6.5 and looks like it is caused by USB3 Port incompatibility of some sort, but I thought I would post the solution anyway just in case anybody else should encounter this and save them some time.
SSH into the ESXI Machine and execute the following & reboot the machine.
Code: Select all
esxcli system module set -m=vmkusb -e=FALSE
