Hello!
The README states that product id precedes vendor id, but the source code for the cp2102 class states the order is the opposite.
Maybe you could find some time to correct the corresponding README line.
Thanks.

I would have thought because this is a user space thing, its less linux tied.
I have a need to go from 250k baud to 2m baud during run time. Any suggestions?
I came up with this but I'm missing the data because it is sent so quickly in between baud changes:
const fillBuffer = (chunk) => {
for (let i = 0; i < chunk.length; ++i) {
buffer[pointer] = chunk[i]
pointer += 1
if (pointer === 4096) {
console.log('warning: buffer wrapped')
pointer = 0
}
}
}
const initConnection = async (baudRate) => {
const connection = new CP2102(0x10c4, 0xea60, { baudRate })
await new Promise((resolve, reject) => connection.on('ready', resolve))
connection.on('data', fillBuffer)
return connection
}
let connection = await initConnection(250000)
...
await new Promise((resolve, reject) => connection.close(resolve))
connection.off('data', fillBuffer)
connection = await initConnection(2000000)
