Thankfully things are a bit better these days. You can now walk into your local dealership and purchase a 165 horsepower 2020 Triumph Rocket 3 R. That 165 horsepower can take you from 0 to 60mph in 2.73 seconds if your drag racing skills are up to the task.
Take a look at the 51 second video below. Not only is the acceleration rate amazing, but Triumph is boasting improved handling, braking and ground clearance. The test rider accelerates faster than a McLaren, does monster wheelies, back into corners supermoto style, and drags his knee around the racetrack. Your results may vary.
By 1939, the year that those two records came out, there were an estimated several hundred thousand jukeboxes in place across America, in bars and taverns, diners and soda shops, and numerous other establishments. According to jazz scholar Eddy Determeyer, the boxes utiized 30 million records that year, and their success caused a national coin shortage.
The World War II years brought a temporary halt to new jukebox production, owing to wartime needs, though jukeboxes remained highly popular, and even found a new home in youth centers that were opened to counter the growing problem of juvenile delinquency. Jukeboxes also played a part in sparking the American Federation of Musicians' 1942-1944 recording ban. Union leader James C. Petrillo and others were concerned that jukeboxes (which also required no royalty payments), as well as radio and phonographs, were usurping live performance employment opportunities for musicians.
Whatever one called them, they continued to be highly influential throughout the 1950s. Tommy LiPuma, an aspiring musician in those days who went on to become a renowned record producer and head of Verve Records, late in his life recalled a seminal jukebox experience:
If the linux kernel recognizes the devices and loads the driver correctly, the error must be in programs that communicate with the external device, or that a program initiates the port and an incorrect value is set for the respective port.
Now I have tested a bit on VenusOs 2.82 Lage and rs485 devices, and can state that with my devices based on ch341 usb to rs485 it works as you explain, but somewhat more random. If I stop the serial-starter daemon is all as it should be, with full control on 6 x rs485 devices. I can configure everyone as I want and send and receive data on all of them.
Just for fun on pi4 I plugged in 3 pcs more total 9 x rs485 and linux detects everyone and everyone works. So it is clear that the error lies in the software a place. Tested on pi3b + with 4 x usb to rs485 + 4 x usb to ttl which also works fine
Oh, what I notice positively, my PI4 doesn't seem to be that busy anymore. I previously had sluggish behavior on the remote console and in Path Browser. Virtually stuck in the flow display and also in the menu. Everything is great now!
so i give up. The whole thing can no longer be explained in normal words. Sometimes it works, sometimes not. I still think the code is poorly executed here. Imagine if every manufacturer of a jukebox or whatever only works with their own USB adapter. Terrible.
