[DragonFlyBSD - Bug #2822] USB 3.0 stick throws "reading primary partition table: error accessing offset 000[...] for 152" error, while the stick works on any other OS I tested

Issue #2822 has been updated by revuwa.


Of course I tried USB 3.0 ports, too (with the same problem).
This was my first idea, because I tried to put my USB 2.0 stick into USB 3.0  port and this doesn't work, too (but is not my problem here).

My USB 3.0 stick (fat32 formatted) works great on other Windows / Linux and OpenBSD operating systems. On the stable DragonFly (and after that on "DragonFly-x86_64-20150601-DEV-v4.1.0.1545"-image, I get the usual message instantly after putting it into one of my USB 2.0 ports (of my ThinkPad X200s):
# umass0: <vendor 0x13fe Patriot Memory, class 0/0, rev 2.10/1.00, addr 2> on usbus3
# disk scheduler: set policy of da8 to noop

now I have to wait a few seconds and get the rest of the usual messages:
# da8 at umass-sim0 bus 0 target 0 lun 0
# da8: < Patriot Memory PMAP> Removable Direct Access SCSI-6 device 
# da8: 40.000MB/s transfers
# da8: 30176MB (61800448 512 byte sectors: 255H 63S/T 3846C)

after a few seconds more I get the final message:
# da8: reading primary partition table: error accessing offset 000000000000 for 512
which prevents me from mounting/using the stick.

Other (USB 2.0 sticks) working great instead.

I've attached dmesg and pciconf -lv output. Please let me know I I could provide any more details.

Over IRC I got a hint that it could be "an unfortunate collaboration of the usb stack and our cam", which could probably helpful.

Thanks in advance for any help.
