I can confirm this behaviour:

I have following USB devices working in this system:
* 1 USB HDD (USB - EIDE bridge)
* 1 Transcend JetFlash V10 - 8 GB flash drive
* 1 Sony Ericsson W800i mobile phone (memory stick available as USB drive)
* USB Mouse

But the following flash drive does NOT work:
* Transcend JetFlash V30 - 8 GB flash drive

(The drive works fine in windows/linux, and has a standard FAT32 partition)

On plugging it in, the following appears in /var/adm/messages:

Apr 11 15:14:49 spot usba: [ID 912658 kern.info] USB 2.0 device (usb58f,6387)

However the device isn't "recognized" and is neither mounted nor there are 
entries for it in /dev/dsk or /dev/rdsk. The device is *not* reported by 
"rmformat"
