FWIW because you do so professionally I'd factor in the time you spend too versus buying hardware (e.g. USB dongles) or even laptop, ideally reselling the old one. I don't know your rate or how much you can buy VAT free or your income at the moment, only that in your context this is also a business decision so you have to consider the ROI of "just" moving on with another hardware, selling the old one and with the time earned (if work is available) get another paid task instead of tinkering.
