But writing speed seems slow to me, I measure about 56 to 64 kbyte/s transfer
rate only:

That seems pretty slow. I get about 2.7MB/s on writes. How are you writing to it?

port 5 addr 2: high speed, power 250 mA, config 1, Mass Storage Device(0x6362), Generic(0x058f), rev 1.10

This is against 50x CF
