Lost connection to USB

Postby maniecki » 31. Jul 2021, 12:43

Hello everyone. I have a fiber laser marking machine that only has 32 bit controls, so I use VirtualBox.
When I use USB 2.0 everything is fine. The problem occurs when I switch to the USB 3.0 controller.
Initially the machine runs normally, but after about 20 minutes it disconnects and I get the error "BJJCZ USBLM-V1 'with UUID {long code} is busy with a previous request. Please try again later."
Only when I restart the guest system, it can be used again, but for a short time and the problem reappears.
I would like to use USB 3.0 because everything works faster.
Host OS - Windows 10 64 bit
Guest OS - Windows 7 32 bit


- I created Virtualbox USB Filters
- There is no UpperFilters entry in the registry
- Extension pack installed

I am asking for help, what can be done to keep the machine working on USB 3.0 and not losing connection with the guest.
Thank you in advance for your help.

Per USB basics and troubleshooting, "busy with a previous request" means:
something else (most probably the host) is using the device.

So in some fashion your device is disconnecting from the VM and reconnecting to the host.

Why this is happening would at least need a log from the VM when the disconnect occurs. See the USB tutorial post 8 and provide the requested information. Note also that Windows 7 needed drivers to handle USB 3, I'm assuming you installed such drivers in the VM.

FWIW forum guru advice is to not try to control real-time-ish robot control devices with VMs. I have a Shopbot, I wouldn't dream of trying to run it with a VM. Physical control hardware is important for the outcome of the project, so as to not lose step because the VM or comms glitched. Since you're using Windows 7, there's still enough decently-priced refurbished PCs from the 7 era that you could get a couple and keep one active, one in reserve, for more solid control of your laser burner. A PC with native USB3 or a PCIe slot for a USB3 card would probably work quite well.

Thank you for your response. I use VB to control the machine because I have one computer on which I use graphics programs and I do all the operations and it would be difficult to have another computer with a 32 bit system, and I like to make my work easier :)

Below are the logs. Please check if they are correctly read. I have doubts whether I entered the query "VBoxManage showvminfo" <Your_Virtual_Machine_Name> "" correctly because an error appeared.

Please repeat the "VBoxManage showvminfo" command without the <>'s:

VBoxManage showvminfo "fiber"

Also, please identify which device in "usbhost" is the laser device.
