Hi Giorgi,

Thanks for the update and taking further action wrt filing a Trouble Report. Will monitor the same.

Regarding your question, we rented this particular virtual macOS remote machine as “a dedicated server” (virtual) from macincloud.

Please let me know if further information is needed.

Regards,
Sumit

Adding possibly relevant information.

When we tried to connect the iPhone from a different Windows 10 client machine, then we could see iPhone appearing in the Finder on the remote macOS machine. But, accidentally, my laptop went into sudden sleep mode (because of low battery) and subsequently we reached the same situation as above (green dot on the local machine but nothing visible in the remote machine’s Finder). Again, I could see USB port blocked related errors in the dmesg output.

It may be a problem with sudden/improper disconnection of the client machine (or the devices) and remote server somehow not able to release relevant USB port (blocked port status survives system reboots and NoMachine installation and reinstallation).

Thanks for your efforts!

Best regards,
Sumit

Hi Giorgi, by way of introduction, I am Pranay’s supervisor. Here are answers to your questions: –

1. We see some MacOS “virtual” USB devices in the “System Report” provided on remote MacOS BigSur virtual machine (VM) rented in the cloud. Attaching screenshot.

2. We see “VMware Virtual USB Keyboard” and “VMware Virtual USB Mouse” devices (that are present on remote MacOS as mentioned above) in the NoMachine “Remote USB Devices” on the local Windows client machine. Attaching some relevant screenshots.

I tried connecting to my home Windows computer from the cloud machine using NoMachine, but I believe this will require some firewall config changes. Please let me know if remote MacOS “client” logs are necessary then we will arrange the same.

Moreover, I observed following puzzling message in the “dmesg” logs (shared by Pranay above): –
===========
04345.049832 nxusbd@: AppleUSBHostUserClient::openGated: could not open provider VMware Virtual USB Hub. provider already opened for exclusive access by a kernel client
===========

Should above message about “provider Hub being already reserved for exclusive access” be of concern to us?

Since its VM, we have no knowledge about any “physical” USB devices being connected (no reason to believe that our cloud service provider will do this).

Many thanks for your help!

Best regards,
Sumit
