I had been frustrated for years with the dire support for connecting mobile phones (cellphones..) on Linux. Bluetooth support to phones was patchy, to say the least, and has been completely re-written for KDE, but still has very limited functionality.. I can (just about) connect to my Samsung Android phone, but can only transfer files to the … Continue reading →
I had got tired of trying all the so-called ‘recommendations’ for fixing USB hub connectivity on the Raspberry Pi – including some from people who did not actually own one.. And yes, I do have the correct voltage power supply etc. etc… So – I was happy to see that there was -at least – a potential … Continue reading →
After many fruitless attempts to cobble together a working USB hub setup for the Raspberry Pi, I came to the conclusion – after trying all the USB/mains power adapters I had (from various phones and other accessories), that the power supply made a significant difference to the behaviour of the Pi.. With some adapters, I had to … Continue reading →
Thought I would try a couple more options, just in case.. First, I confirmed that the USB sound card works connected directly to one of the Pi USB ports (using a USB extension cable): usb 1-1.2: new full speed USB device number 13 using dwc_otg usb 1-1.2: New USB device found, idVendor=0d8c, idProduct=000c usb 1-1.2: New USB … Continue reading →
Another option I just tried turned nasty very quickly… I wondered what would happen if all external USB devices were connected via the (powered) hub, but the answer was soon apparent: usb 1-1.3.1.1: reset low speed USB device number 6 using dwc_otg usb 1-1.3.1.2: reset full speed USB device number 7 using dwc_otg INFO:: periodic_channel_available: Total channels: … Continue reading →
After successfully installing the Adaptec SCSI 320 card (and running out of PCI-E slots..) and connecting the ‘new’ HP LTO-3 tape drive, I have been enjoying the deja-vu feeling of using SCSI again, after many years… I remember the pre-USB and pre-Firewire days, when CD-drives and scanners (and expensive disks) were all connected using SCSI… Printers – … Continue reading →
