Every _non-bogus_ reader.
For example the Feitian SCR301 [2] is bogus and can't support CASE 2
APDU with Le=0 (256 bytes). That is why this reader is listed in the
"unsupported" list of my CCID driver.

The reader above has a problem with Le=256. Le=254 should work and the
reader should not have a problem with MyEID.

I don't know which readers have problem with MyEID. An explicit list
of bogus readers would be great so that users can avoid buying such
readers.
