Detecting usb stick in freebsd
I inserted a 8GB usb stick in a number of machine with FreeBSD 7.1, but the medium was not detected:
Code:
$ dmesg | grep MB
usable memory = 4263022592 (4065 MB)
avail memory  = 4082540544 (3893 MB)
pci0: <serial bus, SMBus> at device 31.3 (no driver attached)
ad0: 238475MB <WDC WD2500BEVT-00ZCT0 11.01A11> at ata2-master SATA300
da0: 40.000MB/s transfers
cd0: 3.300MB/s transfers
usable memory = 4280356864 (4082 MB)
avail memory  = 4099862528 (3909 MB)
pci0: <serial bus, SMBus> at device 31.3 (no driver attached)
ad0: 238475MB <WDC WD2500BEVT-00ZCT0 11.01A11> at ata2-master SATA300
cd0: 3.300MB/s transfers
da0: 40.000MB/s transfers
usable memory = 4280356864 (4082 MB)
avail memory  = 4099862528 (3909 MB)
pci0: <serial bus, SMBus> at device 31.3 (no driver attached)
ad0: 238475MB <WDC WD2500BEVT-00ZCT0 11.01A11> at ata2-master SATA300
cd0: 3.300MB/s transfers
da0: 40.000MB/s transfers

Furthermore, the usb stick gets very hot after about 5 minutes, probably well over 50C, which is abnormal. This happens on all machines with FreeBSD. da0s1 is not available, as is da1s1 etc. So even if I could mount the stick, it is unclear where to mount it to. Perhaps someone has a suggestion?

adw

ADW(4)							   BSD Kernel Interfaces Manual 						    ADW(4)

NAME

     adw -- Advansys PCI 16bit SCSI Host adapter driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device pci
	   device scbus
	   device adw

DESCRIPTION

     This driver provides access to the 16bit SCSI bus connected to the Advanced Systems Products, Inc.  ASC3550 Ultra, and ASC38C0800 Ultra2,
     SCSI Host Adapter chips.  Both chips support, synchronous transfers (20MHz and 40MHz max respectively), 16bit transfers, tagged queueing, and
     up to 253 concurrent SCSI transactions.

     Per target configuration performed in the AdvanceWare menu, which is accessible at boot, is honored by this driver.  This includes synchro-
     nous/asynchronous transfers, maximum synchronous negotiation rate, wide transfers, disconnection, tagged queueing, and the host adapter's
     SCSI ID.  The global setting for the maximum number of tagged transactions allowed per target is not honored as the CAM SCSI system will
     automatically determine the maximum number of tags a device can receive as well as guarantee fair resource allocation among devices.

HARDWARE

     The adw driver supports SCSI controllers including:

     o	 AdvanSys ABP940UW/ABP3940UW
     o	 AdvanSys ABP950UW
     o	 AdvanSys ABP970UW
     o	 AdvanSys ABP3940U2W
     o	 AdvanSys ABP3950U2W

SEE ALSO

     adv(4), cd(4), da(4), sa(4), scsi(4)

HISTORY

     The adw driver appeared in FreeBSD 3.0.

AUTHORS

     The adw driver was ported by Justin T. Gibbs from the Linux driver written by Bob Frey of Advanced System Products, Inc.  Many thanks to
     AdvanSys for providing the original driver under a suitable license for use in FreeBSD.
