 Using the same mb and bios with different usb sticks and a hub too:
 
 1.) a sd card reader in a floppy drive:
 
 umass0 at uhub5 port 2 configuration 1 interface 0
 umass0: Ltd Winter Ver1.3, rev 2.00/0.05, addr 2
 umass0: using SCSI over Bulk-Only
 scsibus0 at umass0: 2 targets, 2 luns per target
 sd0 at scsibus0 target 0 lun 0: <USB2.0, CardReader CF RW, 0814> disk removable
 sd0: drive offline
 sd1 at scsibus0 target 0 lun 1: <USB2.0, CardReader Combo, 0814> disk removable
 sd1: drive offline
 
 I insert a sd card after booting and can access it with disklabel and mount it.
 
 2.) Now a usb stick on the usb connector at the front side of the case:
 
 umass1 at uhub5 port 5 configuration 1 interface 0
 umass1: TwinMOS U3 MobileDisk, rev 2.00/2.00, addr 3
 umass1: using SCSI over Bulk-Only
 scsibus1 at umass1: 2 targets, 2 luns per target
 sd2 at scsibus1 target 0 lun 0: <TwinMOS, U3 MobileDisk, 6.16> disk removable
 sd2: 1954 MB, 1009 cyl, 128 head, 31 sec, 512 bytes/sect x 4003711 sectors
 cd1 at scsibus1 target 0 lun 1: <TwinMOS, U3 MobileDisk, 6.16> cdrom removable
 
 Works fine too.
 
 3.) The same stick, but using a usb hub:
 
 uhub7 at uhub4 port 3: Atmel Standard USB Hub, class 9/0, rev 1.10/3.00, addr 2
 uhub7: 4 ports with 4 removable, self powered
 umass1 at uhub7 port 1 configuration 1 interface 0
 umass1: TwinMOS U3 MobileDisk, rev 2.00/2.00, addr 3
 umass1: using SCSI over Bulk-Only
 scsibus1 at umass1: 2 targets, 2 luns per target
 sd2 at scsibus1 target 0 lun 0: <TwinMOS, U3 MobileDisk, 6.16> disk removable
 sd2: 1954 MB, 1009 cyl, 128 head, 31 sec, 512 bytes/sect x 4003711 sectors
 cd1 at scsibus1 target 0 lun 1: <TwinMOS, U3 MobileDisk, 6.16> cdrom removable
 
 Which works fine too.
 
 => No problem here with 5.99.02, but it also worked fine with 4.99.73

 Btw, it is a SB750 which you and I have.
