I use a USB key and devb-umass driver. The first time all work fine but if I
plug out my usb key then i plug in again, the logical mount access is not
create.
I show information I get :

----> It seem to mount to early when devb-umass find the usb key the second

Can you analyse it or suggest some options to use USB KEY ?

Thanks for your help, I had already try multiple options before ask some
help. pnp option doesn’t make it work…
After other QNX problem it seem to be know despite one year by QNX
developper… the solution exists but it is not yet implemented…
perhaps next year…
The workaround to do is make a mount command from application…
I transfer answer i get from your service… I let you imagine what
developper we are think about !
“Yes, for 6.3 USB automouting works only the first time (this is known as
PR/18901). It was fixed a year ago but not schedulled for any release
yet. You can workaround by performing the mount manually (after insert).”
