The orange micro ones we've got have a big sticker on them saying 'orange micro'... these dont... unless there were an unbranded batch supplied. The part numbers and serial numbers are totally different between the two types of card. The SN on the orange cards start 'W2053120', the unbranded UH2-225 start '400018001-00' p/n 'A00919-D14' compared to the lists of sn's and pn's i have, it would indicate that there are probably not orange usb...

cheers
