inexpensive cheap BlueTooth adapter roundup

Filed under: DIY,Geeky goodness,HardWare,Ubuntu — Sagacious Himself @ 1:27 am

Ever wonder about the quality of cheap bluetooth dongles on amazon?  I did so I bought a few dozen.

soooo many junky non upgradeable  Cambridge Silicon Radio flavors.  My favorite junk CSR 0a12:0001 causes no problems until trying to pair then system hang — not so great for proximity login.

0a12:0001 [ASIN:B003VWU79I, merchant:A2T2LRVG0LYFAA, $2.5]

Most play well with the powered USB2 hub:

05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB,  Macally TriHub7, ASIN:B001DBF07S

Other fun hardware playing well on the hub

045e:001d Microsoft Corp. Natural Keyboard Pro
1532:000d Razer USA, Ltd

Hardware that does not play well on the Raspberry Pi directly or on the hub:

045e:001d Microsoft Corp. Natural Keyboard Pro — massively repeated letter strings and numerous letter dropouts

I don’t often experience commercial breaks but when I do I do something else. For everything else there’s sick beard.
