A 16G USB flash memory stick here works with 8.3-RELEASE but fails (on same
PC & port) to create /dev/da* on FreeBSD-9 & 10. (devd running on all3)
What should I change for the stick ?
What can we change on FreeBSD so similar devices dont fail ?

On 8.3-RELEASE LED stays on, dev/da* appera, & can mount,.
On 9.2 & 10.0- Releases, the LED flashes faster than a whirling dervish,
but no /dev/da*

9.2-RELEASE shows:

10.0-RELEASE on same PC shows similar, as does another 9.2 PC

9.2 devd -d does start doing the right thing eg:

My /devusb/hama16g@ -> /dev/da0s1 (works for other sticks) is left
dangling as no /dev/da* to point to.

2nd PC usbconfig shows:

( BTW Seems a lot of power for a stick ?  A same size 16G USB3 stick (on
same USB 2 socket) reports ugen5.2: <Mass Storage Device JetFlash>
at usbus5, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON (500mA), & the
USB3 stick mounts OK. )

Per man usb_quirk, I tried a reboot with usb_quirk_load="YES" in
/boot/loader.conf , did not help.

Rebooted with 8.3-RELEASE, stick works.

BTW This "Hama" stick is a very lightly used device, not worn out,
In case anyone else has one to try, it's:
Product code 34 090894, 10 Euro from Mueller, Munich, Germany 2012_10_11 
Cardboard marked USB2 6 MB/sec Bar Code 4 047443 144492.

Cheers,
