Should have spoke to you first. Managed to miss TI part in original search. Must admit USB connectivity is not my strongpoint. I need the chip to allow a recording of Audio Data over a period of hours (8 - 12). The current Laptop uses a NS Geode processor with on chip sound. Unfortunately this seems to conflict with his software, and drops out after about 2 or 3 hours. Are the two chips overkill for these simple requirements, both manufacturers are much happier to boast about output capabilities.
Thanks again
