How to detect USB device name without using any additional tools ?

Is 'cat' considered a package? cat /proc/bus/usb/devices works fine for me.

Hi Sato,

If I do a cat /proc/bus/usb/devices I get the following dump.

linux:~ # cat /proc/bus/usb/devices T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2 B: Alloc= 0/900 us ( 0%), #Int= 0, #Iso= 0 D: Ver= 1.00 Cls=09(hub ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1 P: Vendor=0000 ProdID=0000 Rev= 0.00 C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr= 0mA I: If#= 0 Alt= 0 #EPs= 1 Cls=09(hub ) Sub=00 Prot=00 Driver=hub E: Ad=81(I) Atr=03(Int.)

How to identify the device name from this.?

Whether it is /dev/sdb* or /dev/sda* or specifically sda1 or sda2 etc.

You can put a dmesg as soon as u put the USB device. and find out the device name.... mostly it would sda1 or so... checkout... the dmesg sudhakar :-).

Initializing USB Mass Storage driver... scsi0 : SCSI emulation for USB Mass Storage devices usbcore: registered new driver usb-storage USB Mass Storage support registered. usb-storage: device found at 3 usb-storage: waiting for device to settle before scanning Vendor: Generic Model: 2.0 Reader -0 Rev: 1.00 Type: Direct-Access ANSI SCSI revision: 00 usb-storage: device scan complete SCSI device sda: 990976 512-byte hdwr sectors (507 MB) sda: Write Protect is off sda: Mode Sense: 03 00 00 00 sda: assuming drive cache: write through SCSI device sda: 990976 512-byte hdwr sectors (507 MB) sda: Write Protect is off sda: Mode Sense: 03 00 00 00 sda: assuming drive cache: write through sda: sda1 Attached scsi removable disk sda at scsi0, channel 0, id 0, lun 0 FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!

In this dmesg u cld see the device name and here in this case the device is sda1. Hope this helps u.
