What you're asking for is a mass-terminated device - something that allows you to connect via cable. There are such devices for USB, including the
USB-6225,
USB-6255,
USB-6251 and
USB-6259. There are multiple variants of these devices, but if you use the mass-terminated version, connectivity is provided through one (6251) or two (6225, 6255, 6259) 68-pin SCSI II connectors. To maintain signal integrity, it's recommended to use the SH68-68-EP cable to connect up to any of the 68-pin MIO connector blocks.
If you prefer custom connectivity solutions, you can consider making a custom cable to connect up to the SCSI connectors or consider the
SH6850 cable.
Finally, you could consider the USB M Series OEM devices. As previously mentioned, those come without a shielded casing and provide connectivity directly through IDC headers. There's an excellent
OEM user guide giving you information on dimensions and connectivity should you choose to go that route.
