I'll answer myself... I'd assume this is because usbmon shows all usb
activity and not just that from user space usbfs calls. It would still
be nice to have a good way to correlate the logs beyond manually
matching up requests and responses.
Looking at the logs with that in mind, what it looks like to me is:
- kernel starts an enumeration process
- vmware claims the interface and resets it
- vmware starts its own enumeration calls
- vmware resets the interface again
- vmware continue enumeration calls
Its also look like the kernel may be doing its own enumeration again
after each reset. To be expected?
Assuming this analysis is accurate, I guess that answers my question. I
wonder what vmware would say about all this.
