Fail to auto probe USB driver after USB pull out and re plug in

Hi Michael:

We found that the device fails to auto probe USB driver (usblp) after re-plug in, when vhusb service is running. (but shut down the vhusb server will behave as we desired),
Is this a known issue? How can we solve this?

Thanks!
