Missed that. None of the local shops in Vancouver has a USB 3 adapter card in stock. Amazon and etc. offer them of course. 3.0 is more numerous than 3.1 which is > 3.2. > Step 2: is your USB3 chipset from Etron or ASMedia? It won't > work with those. See following. > Step 3: Does lsusb show the device? peter@dalton:~$ lsusb -vs 005 | head Couldn't open device, some information will be missing Bus 003 Device 005: ID 1164:f533 YUAN High-Tech Development Co., Ltd Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 2.10 bDeviceClass 255 Vendor Specific Class bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 The full output is at http://easthope.ca/lsusb.vs5.txt .

I suggested the Startech USB32VGCAPRO which shows Mac support. https://www.startech.com/AV/Converters/Video/usb-3-capture-device-vga~USB32VGCAPRO Staples doesn't sell that but lists the Startech USB3HDCAP. Someone decided to substitute. (This is the public sector. Throw money until something works or the administration loses interest.) We should aim for an adapter claiming to support UVC and Linux. Two examples. https://inogeni.com/product/vga-to-usb-3-0 https://www.epiphan.com/store/avio-hd/ (https://inogeni.com/product/hdmi-dvi-to-usb-3 can not convert analogue to digital. Therefore can not be used with a passive VGA to DVI adapter.) USB in a disused Mac might work. For a PC with Debian buy the USB adapter sold or recommended by the vendor of the converter. Additional tips always welcome. Thanks, ... P. -- https://en.wikibooks.org/wiki/Medical_Machines Tel: +1 604 670 0140 Bcc: peter at easthope. ca
