I have a very strange problem with usb sticks. When i plug in the first one a /dev/sda node is createt but never a /dev/sda1 node. The next plugged device has good chances to get a /dev/sdb1, but its not sure. I tryed out this with any different sticks, so I can say this problem is not specific to a single device. Here the dmesg from a first plugged device: usb 1-1.2: new full speed USB device using s3c2410-ohci and address 4 usb 1-1.2: New USB device found, idVendor=16c0, idProduct=0500 usb 1-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 1-1.2: Product: WETTER INFO BOX 2 usb 1-1.2: Manufacturer: MOERER usb 1-1.2: SerialNumber: 0000070904 usb 1-1.2: configuration #1 chosen from 1 choice scsi0 : SCSI emulation for USB Mass Storage devices scsi 0:0:0:0: Direct-Access MOERER WETTER INFO BOX2 1.00 PQ: 0 ANSI: 0 sd 0:0:0:0: [sda] 1537 512-byte hardware sectors: (786 kB/768 KiB) sd 0:0:0:0: [sda] Write Protect is on sd 0:0:0:0: [sda] Assuming drive cache: write through sd 0:0:0:0: [sda] 1537 512-byte hardware sectors: (786 kB/768 KiB) sd 0:0:0:0: [sda] Write Protect is on sd 0:0:0:0: [sda] Assuming drive cache: write through sda:<7>usb-storage: queuecommand called sda1 sd 0:0:0:0: [sda] Attached SCSI removable disk .... a little bit later: [root@FriendlyARM /]# ls -l /dev/sd* brw-rw---- 1 root root 8, 0 Jan 17 15:26 /dev/sda brw------- 1 root root 179, 1 Jan 17 2010 /dev/sdcard has anyone a idea?
