Hi,

I need some help,
I need a solotion to implement in VB CRC5-USB algorithm to calculate checksum over one string.
I have a string from 5 characters (ex: 4RTE2) and I must to calculate at the end 1 digit will be checksum over string (4RTE2X).
I know that polynomial for CRC5-USB is X^5 + X^2 + 1, but didn't figure how to apply this polynomial over the string to get checksum digit.
I did a lot search over internet, I dont understand how to calculate.
Maybe someone have some idea, example.

Thnaks in advance for any idea
