PNY P-SDHC4G4-RF3 working fine after kernel patch installed as per
http://www.internettablettalk.com/wi..._to_a_computer
Main problem was I cannot find an underline key on my keyboard, so I renamed with tildes.
Transferring contents from the old Sandisk Ultra 2Gb to my PC took 45 minutes; it took 9 minutes to transfer those same files back to the new PNY SDHC card inserted to PC with Sandisk's SDDR-113 USB card reader/writer.
The stutter afflicting M4A music played from the slower card isn't
in evidence.
