HELP: USB 3.0 ExpressCard not working on MacBook Pro with 10.13.6

[JaesonK]

My old USB 3.0 ExpressCard died. I'm not sure what chip it used. The card was labelled NanoTech ExpressCard/34 USB3.0. It worked perfectly, until it didn't.

I'm trying to use a replacement, but performance of my external USB3 RAID (OWC Mercury Elite Dual) is extremely slow. It's unusable with the new card at the moment. The RAID is faster on the USB2 now. No errors reported with the RAID. I tried a new USB3 cable too. The USB3 card is labelled AKE 2 Port USB 3.0 expressCard and says NEC UPD720202 Chip.

My 17" MacBook Pro is a late 2011 model with 16GB and running High Sierra 10.13.6.

System Report USB says:

USB 3.0 Bus:

Host Controller Driver: AppleUSBXHCIPCI
PCI Device ID: 0x0015
PCI Revision ID: 0x0002
PCI Vendor ID: 0x1912

System Report PCI says:

Is there some kind of conflict? Do I need a different driver? If so, where can I find it and how do I install it?

Yes there is a conflict, macOS doesn’t work with Renesas based USB chipsets. You need to use a card with an Intel, ASMedia or Fresco Logic chip, which are compatible with macOS. There are no native USB kexts that work with the Renesas card.

Provide a link to the Renesas (NEC) card you are currently using and someone might be able to provide a link to a card that will work in macOS.

A card like this should work, as it uses a compatible Fresco Logic (FL1100) chip.

Thank you for the suggestions! I'll look for a card with the appropriate chips.

Until I get a compatible replacement card, I can use FW800 with my MacBook Pro and the OWC RAID, it has USB3 & FW800.

FYI, my 2011 MacBook Pro can only use the narrower 34mm size card, restricting it to 2 ports, rather than the wider 3 port version in the ebay link.

Thanks again!

Firewire may be your best option in the long run, as I can't find a compatible USB3.0 34mm Express Card. They all seem to use NEC/Renesas chips.
