one of my vm randomly freezes. I checked syslog and found the following entry at the time when the VM freezes:

Code:
Nov 13 11:02:08 pve kernel: [4448894.065807] usb 2-1.8: USB disconnect, device number 4
Nov 13 11:02:08 pve kernel: [4448894.289288] usb 2-1.8: new full-speed USB device number 7 using ehci-pci
Nov 13 11:02:08 pve kernel: [4448894.404217] usb 2-1.8: New USB device found, idVendor=0403, idProduct=6001, bcdDevice= 6.00
Nov 13 11:02:08 pve kernel: [4448894.404220] usb 2-1.8: New USB device strings: Mfr=1, Product=2, SerialNumber=3
Nov 13 11:02:08 pve kernel: [4448894.404222] usb 2-1.8: Product: FT232R USB UART
Nov 13 11:02:08 pve kernel: [4448894.404223] usb 2-1.8: Manufacturer: FTDI
Nov 13 11:02:08 pve kernel: [4448894.404225] usb 2-1.8: SerialNumber: AB0JTAI8
Nov 13 11:02:08 pve kernel: [4448894.406762] ftdi_sio 2-1.8:1.0: FTDI USB Serial Device converter detected
Nov 13 11:02:08 pve kernel: [4448894.406795] usb 2-1.8: Detected FT232RL
Nov 13 11:02:08 pve kernel: [4448894.407435] usb 2-1.8: FTDI USB Serial Device converter now attached to ttyUSB0

I did not unlug the USB device. I've no idea where this comes from. I found comparable post where user complain similar issues with USB resets cauing VM freezes but I could'nt find any reason.
What can I do to investigate further?
