You look completely confused :-(
readcd is known to work properly with any SCSI transport a kernel might
support.
If _you_ have problems with USB, then you are using a broken kernel or
a USB<->ATA adaptor that does not work properly. There are a lot of them
it you like to have USB-2...
It is a _real_ bad behavior to write wrong and blanket acusations :-(
If you had documented your specific problem in a useful way, people could have
directed you to the real problem (whether it is caused by a bug in the Linux
kernel or in a bug in the USB<->ATA adaptor). There is definitely no problem in
readcd that causes any problem with USB. I know this from own recent experience
as I did a lot of USB-2 testing recently. I ran into a kernel bug on Solaris 10
that has been fixed within 10 days. I however don't see why I should even try
to contact the Linux kernel developers that are known to only piss on people
who send them well investigated bug reports.
As a hint: the main problem with USB-2 is rotten hardware!
If you like to succeed in using USB-2, buy a 15 Euro NEC chip based PCI card and
use a recent Solaris 10 kernel. The VIA USB-2 chips are known not to work
as documented on the other side. The only USB-2<->ATA Adaptor that is currently
known to work correctly is the ALi M5621 A1
If you don't know how a useful bug report looks like, read

CONCLUSION: Please finally stop to post wrong statements about readcd.
