 mount USB storage device in FreeBSD |

from the dept.
Hi, I have a question about mounting a USB memory chip (64 Mb capacity). It works fine in any windows PC. But I tried to mount it in my FreeBSD4.3 box.
I read some tips from the internet that some people use the following command to mount it as
mkdir /mnt/usb
mount -t msdos /dev/da0s1 /mnt/usb
So I tried this way. First, I insert my memory chip into a USB port on FreeBSD4.3 box.
The dmesg.boot shows :
umassQ: USB Solid State Disk rev 1.10/1.00, addr 2
da0 at umass-sim0 bus 0
da0:<DIANMA STORAGE KING\242\362.11>
Removable Direct Access SCSI-2 Device
da0: 650kb/s transfers
da0:63MB (129024 512bye sectors 64H32S/T63C)
Then I tried to mount it as
mkdir /mnt/usb
mount -t msdos /dev/da0s1 /mnt/usb
But the console shows:
da0:( umass-sim0:0:0:0):READ(06),cbd:800010
da0:( umass-sim0:0:0:0):ILLEGAL REQUEST ASC:20,0
da0:( umass-sim0:0:0:0):Invalid command operation code
da0:reading primary partition table:error reading fsbn0
msdos: /dev/da0s1: input/output error
So it seems the mounting is not successful. So I tried this way:
mount /dev/da0s1 /mnt/usb
This time the console shows:
da0:reading primary partition table:error reading fsbn0
msdos: /dev/da0s1: input/output error
I know there must some thing wrong with my mounting command, but I do not know what it is. I would appreciate it very much if anybody can help me on that.
Thanks very much.

Hi Jennifer,
I have only been able to get my USB SmartMedia reader to work properly in FreeBSD-4.7 and 4.8. I have also tried 4.5 but it didn't work until after I upgraded.
The command I successfuly use for mounting the media is:
mount -t msdos /dev/da0s1c /mnt/usb

Hi, Jason
You are very right there. FreeBSD people confirmed that FreeBSD4.3, 4,5 not support such "new Generation" stuff.
So I will find a chance to follow the advice you wrote in the article:
Re: upgrade from 4.3-RELEASE
To SAFELY upgrade our working disk.
I will choose 4.8 version, as it is a stable one.
Wdyr?
Jennifer

I think FreeBSD-4.8 is good choice. I haven't tried 5.1 yet but 5.0 did have problems. If you install 4.8 you shouldn't have any problems. IMHO

device not configured

Hello,
I have been trying to add an external USB drive so I can do a dump to my FreeBSD 4.8 system, but I do not get any dmesg when I plug in the device, (it works in a 7.0 system I have), I cannot find any information on this.
I searched your site, and googled but cannot find anything, can you help?
Thanx,

Re: mount USB storage device in FreeBSD

Thank you so much...It did work..but yeah would like to add one more thing..
in the command
the argument /dev/da1s1 "da*" should be the port where your USB is inserted,and as shown above it was da0...so while typing in the command it should be the port where usb was detected by FreeBSD.
so...
freeBSD# dmesg

(as here the USB was detected at da0...)
The correct command would be..
mkdir /mnt/usb
mount_msdosfs /dev/da0s1 /mnt/usb
