Hello Hans :-)

Yes that helps:

ugen1.7: <HP> at usbus1
umass0: <HP v195b, class 0/0, rev 2.00/81.92, addr 7> on usbus1
umass0:  SCSI over Bulk-Only; quirks = 0x4000
umass0:5:0:-1: Attached to scbus5

# usbconfig -d 1.7 add_quirk UQ_MSC_NO_SYNC_CACHE

da0 at umass-sim0 bus 0 scbus5 target 0 lun 0
da0: <hp v195b 8192> Removable Direct Access SCSI-0 device
da0: 40.000MB/s transfers
da0: 7728MB (15826944 512 byte sectors: 255H 63S/T 985C)

Thank you! :-) What should I do to avoid this manual intervention in future?

I also noticed that with another pendrive I get the device nodes, but
in dmesg I get lots of this messages:

(da0:umass-sim0:0:0:0): PREVENT ALLOW MEDIUM REMOVAL. CDB: 1e 0 0 0 1 0
