    Hello,
    with parallels 13.0.1 (and 13.0.0) i got some strange problem. Usb network adapter LB-LINK BL-WDN600 not recognized as normal device (paralles tools reinstaled few times). Windows driver on parallels 13 windows machine installing also not helped. With parallels 12.2.1 (41615) this adapter working fine. Please see attachments. Same problem with windows 7 x64.
    Any ideas?

    Hi,
    could you please do the next:
    Stop the VM and go to the VM Configuration -> Hardware -> Boot Order -> Advanced and enter the line "devices.usb.loglevel=2" (without quotes) to Boot Flags
    Boot the VM and reproduce the problem.
    Then send a technical data (menu of Parallels Desktop Help -> Send Technical Data) and post here the report number

    Hi,
    please try to enter the system flag "devices.usb.ehc.translate_ss=0" on the next line after "devices.usb.loglevel=2" and check whether this helps. Please send another report if it doesn't.
    If flags helps, remove the unneeded anymore flag "devices.usb.loglevel=2"

    This appears to be an issue of either Windows, or Parallels. Still investigating. Thank you for reporting!
