Is QNX 7.1 USB supported

Postby CAS » 13. Jul 2022, 20:22

I have VirtualBox 6.1.34 installed.
I have a generic QNX 7.1.0 image for x86_64 which can execute simple QNX applications.
I'm attempting to connect a USB device but all devices fail to connect.
Is USB supported on QNX 7.1 guest?
I also can't find any guest additions to install on QNX 7.1 Are they available?

I don't think so.

That's a good question for QNX. You can get the Virtualbox side of the question at USB basics and troubleshooting.

Supported in what sense? USB is a feature of the (virtual) hardware not the Guest Additions, so it's available to all guests provided the host extension pack is installed.

Whether the guest OS understands how to use USB is a different story.

QNX 7.1 looks quite recent but tiny, so if they provide a HAL/BSP for PC hardware (particular OHCI, EHCI or xHCI chipsets) then I'd expect the answer will be yes, they will have generic support for certain classes of hardware. More exotic hardware will require QNX specific drivers, which I'm guessing will not exist, therefore those devices will not work.

If the only reason for your interest in USB is to access storage devices then I'd look to a network share instead. It's how these embedded OS are usually intended to be used.
