Connecting a mining card to laptop using a PCI-E to USB cable

[zzert1234]

I want to use PCI-E to USB cable in order to connect a card to a laptop ( because I don't want to buy dedicated PC for mining  )... So

Is this a product that can do this ? https://www.amazon.co.uk/iXium%C2%AE-Extender-Litecoin-Dogecoin-Compatible/dp/B00J3X88VS/ref=sr_1_2?ie=UTF8&qid=1506122263&sr=8-2&keywords=amd+mining

Are there any potential problems with the miner software or when connecting to the mining pools, given that my setup will use this PCI-E to USB cable. I.e does the card still appear to the mining software as if it is connected to the motherboard ?

wont work.

the usb cable is used to transfer the pcie signals from the mobo pcie slot to the pcie slot on the add in card. it does not use the usb protocol, it just happens to use the usb cable as it has the right amount of shielding and signal wires.

try plugging that into a standard usb port and at best, nothing will happen. at worst, something will fry.

As has been said, it does not work this way. Although those extenders do indeed use a USB 3 cable to transfer data, it is simply a reuse of a commonly available cable and connectors, it does not follow the USB 3 standard for data transfer. Basically a cable is just a cable, made of wires that any protocols can take advantage of. The USB 3 standard requires both ends, usually a peripheral and a USB controller or hub on either side of the cable to operate. In the case of a PCIe extender, there is no USB controller or peripheral, again it is just using a commonly available cable.

For an even simpler analogy, think of using standard two conductor "lamp cord" to wire your speakers. While the lamp cord is designed to run 120V and maybe 8 amps, it also works just fine for feeding your speakers from your receiver. Another example may be using Cat 5 or 6 network cables to run a standard twisted pair analog phone line. Heck, you could even use LAN cable to wire your door bell or many other things. So basically the USB cable is being re-purposed for a specific functionality in the PCIe extender but it is NOT using the USB protocol and will not work with USB ports.
