Is my Digispark broken?

[Maxr1998]

I received my digispark today, but I can't get it to connect to my computer.
When plugging it into my Ubuntu 16.04 machine (64bit, tried all usb ports I have), it always returns this (or similar) error:

Code: [Select]

[  299.409015] usb 1-2.3-port1: unable to enumerate USB deviceI get the same error on my Lubuntu 15.04 laptop.
I even tried it in my Windows 8.1 Pro x64 environment, installed the drivers, but I only get an unknown device in my device manager, which doesn't even disconnect after 5 secs.

Did I receive a broken device? Should I try to return it?
Or is there anything else I could try to fix the issue?

Update: I tried using a powered USB hub now, tried unbinding the USB ehci-pci device (which then fell back to ohci-pci), but it's still the same. My mainboard is an Asus M5 A99X Evo, means an USB 3.0 motherboard. I think I will just contact my seller now and ask for a replacement, if it still doesn't work, I will return it.

Yeah, I'm thinking there's something wrong with those digisparks too... best to get a refund. I'm presuming they're the clone sort, with microUSB sockets, rather than the original Digisump ones?

btw, you should have been getting output like this via dmesg:

Code: [Select]

[Dec15 19:15] usb 1-1.6: new low-speed USB device number 4 using ehci-pci
[  +0.100228] usb 1-1.6: New USB device found, idVendor=16d0, idProduct=0753

I contacted the seller and already got a refund and even can keep the (broken?) device. It looks 100% identical to the official one's, so if it IS a clone, it must be a pretty good one, I guess.
