You say your code works with many different DS’s but fails with a particular one. That’s a strong indication (but not a guarantee) that the problem is in that DS. You can switch to a memory or file transfer or contact the vendor to try to get the bug fixed.
The TWAIN specification says DS’s are required to support native transfers but very few applications use this transfer method. Vendors usually have a suite of apps they use for Quality Assurance testing. This bug would slip right through QA if the DS is not tested with an app that uses native transfers.
