I think the chipset issue may be OK. Vendor ID 0x059b
The chipset is sometimes separate from the reported Vendor ID & Device ID. For example, many external enclosure use Oxford FW400 chipsets, and in this case, the chipmaker Oxford provides customer level firmware. However the OEM manufacturers often use custom firmware that identifies the Vender & Device as something within their own company rather than Oxford. In your case, this USB-to-SATA bridge board is being identified as "Iomega" which to my knowledge doesn't manufacture "chips", they manufacture "enclosures". This means the real chipset would need to be identified by actually inspecting the chip to get the manufacturer & model #.
A Google search of the Vendor ID & Device ID ("0x059b""0x0370") seems to turn up a litany of crash reports, all on Macs. This is a really bad omen, it appears that this external enclosure seems to be involved somehow in crashes of many applications including Final Cut Pro, FileMaker, HandBrake and others. These applications are all HD intensive applications, so it appears you've been doubly unlucky, you have a VIA chipset PCI card that has issues, and you also have an Iomega external USB enclosure that appears to have Mac specific issues that causes multiple HD intensive applications to crash.
Another bothersome aspect is the firmware. Your Iomega drive reports firmware version "1.0f" while others having the exact same Vendor ID & Device ID are reporting different firmware such as "f6.15". Normally identical Vendor ID & Device ID would have identical firmware, and these two version #'s don't seemingly come from the same firmware series. It's possible that Iomega is using multiple chipset manufacturers and hiding this by using identical Vendor ID & Device ID for very different but similar looking products. I think you've got a double whammy mess, and you probably need both a different PCI USB Card and a different HD enclosure.
