Seems there is a bug with firmware on some PixArt mouse controller chips
(these are used in at least some Dell and Microsoft mice and very likely
in others too). From a stackexchange post:
---snip---
PixArt OEM mice are known to disconnect/reconnect every minute in runlevel 1 or 3 if they are not always polled on Linux. An internal buffer overflows, FW crashes, and they reconnect. The default behavior of the usbhid driver is just to wait for interrupts.
Basics: https://github.com/sriemer/fix-linux-mouse
I've submitted the patch for this mouse to the linux-usb mailing list now:
https://marc.info/?l=linux-usb&m=154159427814212&w=2
The kernel boot option usbhid.quirks=0x045e:0x00cb:0x00000400 would also enable HID_QUIRK_ALWAYS_POLL for you.
Another alternative is to activate the gpm service. Then gpm is polling the mouse and you can actually use it on the virtual terminal.
---snip---
No idea how this would translate to OpenBSD drivers (I don't think
we have an equivalent to HID_QUIRK_ALWAYS_POLL). But it does suggest
a reason and mechanism for why it might be frequently detaching.
